CES Wellington services and repairs Classeq CP500 pass-through dishwashers and glasswashers across Greater Wellington, the Kāpiti Coast, the Wairarapa and Manawatū. This page is a short kitchen-facing guide drawn from Classeq’s official documents. It is not a substitute for the manufacturer’s manuals, and we have not re-hosted those PDFs. Check the model on the rating plate: WS (built-in water treatment), AS (twin rinse element) and SR (steam recovery) variants differ from the standard CP500. For the steam-recovery machine, see the Classeq CP500SR manual and quick guide.

What the CP500 is

The CP500 is Classeq’s current pass-through, or hood-type, warewasher — a new generation, not the older P500, and not the undercounter D500. Classeq Australia describes it as a “High Volume Pass Through Dishwasher Or Glasswasher”. Official product pages say it can be commissioned on install as a dishwasher or a glasswasher, and configured for a straight-through or corner location. A 500 mm basket is standard. Theoretical figures in the official user manual are up to 40 racks an hour and 18 plates per rack; Classeq’s product pages also state up to 720 plates an hour as a dishwasher, and up to 1,000 glasses an hour as a glasswasher (25 pint glasses per rack in the product brochure).

Steam recovery is not included on the standard CP500. It is a separate SR variant, sold in Australia as the CP500SR. Shared feature blocks on some marketing pages mention steam recovery; the product body is clear that the steam-recovery unit is a separate purchase.

Official Classeq manuals

These official Classeq documents are published on classeq.com.au and classeq.co.uk. We link them; we have not re-hosted the PDFs.

• Pass-through Warewasher User Manual (document 90002093, Revision D, July 2026), covering the CP500, CP500-WS, CP500-AS and the steam-recovery (SR) variants of those models
• Classeq Australia CP500 product page and the official CP500 specification sheet
• Classeq UK CP500 product page and the pass-through range
• Classeq CP500 product brochure (filename June 2025; the file itself is dated July 2026) and the Classeq product guide, June 2025
• Classeq’s End of Service Process video, labelled for all CP500 models, and the operator video library
• The Classeq app page, which lists all CP500 models among the machines it covers

Some additional user and installation files still sit in Classeq’s UK download centre, which needs a login. The official user manual above is the public operator document this guide is drawn from. An older P500 pass-through, or the undercounter Classeq D500, is a different machine — do not mix those documents with the CP500.

Key specs (standard CP500)

These figures are from Classeq’s official Pass-through Warewasher User Manual (document 90002093, Revision D), unless we say another official document is the source. Confirm them against the rating plate and the documents supplied with the machine on site, because official sheets do not all agree on every number.

• Pass-through warewasher with a 500 mm basket, 18 plates per rack, and 440 mm clear entry height.
• Width 635 mm excluding the handle (734 mm including the handle). Depth 712 mm excluding the handle, or 698 mm to the hood. Height with the hood closed is listed as 1454 mm minimum (with feet); with the hood open, up to 1999 mm.
• Classeq’s June 2025 product guide and the Australian specification sheet list slightly rounded overall sizes of 635 × 699 × 1453/1999 mm (UK guide) or 635 × 713 × 1453–1999 mm (AU sheet). The width and the two hood heights agree in substance with the user manual.
• Factory programmes of about 1.5, 3, 5 and 7 minutes as a dishwasher, or 1.5 and 2 minutes as a glasswasher, as set out under daily use below. Theoretical capacity 40 racks an hour, and up to 720 plates an hour on an optimal set-up.
• Factory-set temperatures: 60°C wash and 82°C rinse as a dishwasher (85°C rinse on the utensil programme); 60°C wash and 70°C rinse as a glasswasher. Operating noise is listed as under 70 dB(A).
• Wash-tank capacity 28 litres and rinse consumption 3 litres in the official user manual. The UK product brochure lists a 30 litre wash tank, so check the documents for the machine on site. The rinse boiler is listed as 9 litres, or 12 litres on AS (twin rinse element) models.
• Fully-loaded weight 170 kg, or 173 kg on AS models (200 kg and 203 kg with steam recovery). Marketing sheets list different net weights, so use the rating plate and the official sheet for the variant you have.
• Standard equipment in the official user manual includes a drain pump, rinse booster pump, detergent and rinse-aid pumps, and a WRAS-approved air break. Product pages also list click-in/out wash arms, double filtration, a colour-coded display, energy-saving standby, and hygiene and service reminders.

Installation and water requirements

Installation must be carried out by a trained professional, following Classeq’s official installation instructions for the machine. We have not copied installer-only procedures here.

The official user manual lists a G¾ inch (¾″ BSP) water connection, a minimum pressure of 2.0 bar, a minimum flow of 4 L/min, and an inlet temperature of 4–55°C, with a 40 mm drain and a drain height of 0–700 mm from floor level. The official Australian specification sheets list some different inlet figures — 11 L/min and a 60°C maximum on the standard CP500 sheet, and 4 L/min and a 35°C maximum on the CP500SR sheet — so installers should follow the documents supplied with the machine.

On electrical supply, official sources do not all list the same figures, so a qualified electrician must confirm the connection against the rating plate and the documents supplied with the machine. The official user manual lists 30 A single-phase (220–240 V) or 12 A / 16 A three-phase (380–415 V) on standard and WS machines, and 22 A three-phase on AS (twin rinse element) models, with total connected loads of 6.58 kW, 9.58 kW or 12.58 kW. Classeq’s later UK brochure lists 30 A, 16 A and 22 A and does not list 12 A. The official Australian specification sheets list different supplies: 20 A three-phase at 6.6 kW, with an optional 15 A single-phase at 2.6 kW, on the standard CP500 sheet; and 20 A three-phase at 9.5 kW on the CP500SR sheet. We have not chosen one of those tables as the only correct figure.

Classeq’s product pages and brochure describe the machines as Wi-Fi enabled with the Classeq portal. Every official Classeq UK page we checked also states that Wi-Fi connectivity is only available on UK machines manufactured after 1st February 2026. We do not claim that every CP500 in a New Zealand kitchen has Wi-Fi. The official user manual also lists Bluetooth on the control panel; Classeq’s app page includes all CP500 models among the machines it covers.

Daily use

The official user manual is meant to be used after the machine has been commissioned. In outline it says:

• Turn the mains electricity and water on. Close the hood, then press the on/off button. The display lights up and the machine starts to fill.
• While it fills and heats, the status indicator flashes amber and the stage display shows progress. When the wash tank is full and the machine is ready, the indicator turns green and the display shows “ready”.
• How long that takes depends on the power rating on the plate and the incoming water temperature. The official manual gives a guide, with incoming water at 16°C, of about 40 minutes on 30 A single-phase or 12 A three-phase, 35 minutes on 16 A three-phase, and 30 minutes on 22 A three-phase.
• The machine always starts on the Standard programme when you turn it on. Use the up and down buttons to change programme, then press select to confirm.
• As a dishwasher, the official factory programmes are Light (about 1.5 minutes), Standard (3 minutes), Intensive (5 minutes) and Utensil (7 minutes). Factory-set temperatures are a 60°C wash and an 82°C rinse; the utensil programme is shown at 62°C wash and 85°C rinse.
• As a glasswasher, the official factory programmes are Light (about 1.5 minutes) and Standard (2 minutes), with a 60°C wash and a 70°C rinse.
• A heat interlock can extend the cycle if the rinse boiler has not reached temperature in those times.
• Rinse loose debris off items, load the 500 mm basket, then close the hood to start the wash. The status indicator turns blue and the display shows that a cycle is running. If you press the cycle button before the machine is ready, the indicator flashes amber and the cycle starts automatically once the machine is ready.
• At the end of the cycle the blue indicator goes out. Open the hood and remove the basket. Do not open the hood while the machine is washing — the official manual warns of a scald risk from wash water at about 62°C. Wares may also be hot when you take them out.

Classeq’s product pages summarise this as: press on, close the hood to start a wash, and watch the display for notifications and troubleshooting. See the official user manual for loading detail, including plates, glasses, utensils, and pots and pans.

End of shift, cleaning and care programmes

The official user manual says it is important to drain the machine down at the end of each working day. In outline: close the hood, press on/off to turn the machine off, then press select to start the drain cycle. The machine drains the wash tank, does a self-rinse and shuts down automatically. After it is empty, Classeq recommends turning off the mains water and electricity, cleaning the machine, and leaving the hood open so the wash chamber can dry.

Disconnect the power source before you clean. Do not use chlorine, bleach or hypochlorite cleaners, steel wool or other abrasives, or a hose, steam jet or pressure washer on the machine. Remove any broken glass or sharp items first.

The official daily interior clean, after drain-down, asks you to:

• remove and clean the top and bottom wash arms
• remove and clean the basket frame
• remove and clean the filters and the secondary filter
• clean the ball in the anti-syphon device with a jet-nozzle spray bottle
• remove debris from the wash-arm bearings
• refit all arms and filters before you switch the machine back on

Wipe the outside with a damp, not wet, sponge, then a stainless-steel cleaner once it is dry. Once a week, the official manual also asks you to take the inspection caps off the wash arms, clear the wash and rinse nozzles, and clean the wash-arm bearings. If the hood starts to feel heavier, it says food-grade grease can be applied to the hood runners with the hood open.

From the shutdown options you can also select a deep-clean cycle, a refresh cycle (drain and refill with fresh water), or a guided descale programme. Follow the on-screen steps in the official user manual. For descale, that programme drains, refills without chemical dosing, then asks you to add descale chemical to the 28 litre wash tank and close the hood; Classeq says the descale chemical must not remain in the machine for more than two hours, and that you should wear the personal protective equipment given on the chemical packaging. We have not invented any other descale recipe. Classeq’s End of Service Process video is labelled for all CP500 models.

Chemicals and water treatment

Detergent and rinse-aid pumps are fitted as standard on all models in the official user manual. Use commercial warewasher-grade chemicals. If wash results are poor, or you are changing chemicals, consult your chemical supplier and, if needed, book a technician to check calibration.

Built-in water treatment is the WS option; it is not fitted on a standard CP500. Standard machines need an external water-treatment solution if the site water requires it. For options we install and service, see commercial water filters and Kitchen Talk on water treatment.

If your machine has built-in water treatment, the official user manual shows a low-salt warning on the display when the reservoir is low. Refill it promptly with granulated water-treatment salt (maximum grain size 7 mm). Salt tablets are not suitable. Do not put detergent or rinse aid in the salt reservoir, and do not run the machine with the reservoir empty. The official refill steps are: open the hood, remove the salt-reservoir cap at the front right, fill with granulated salt using the funnel supplied, wipe away any spilled salt, refit the cap so it sits flat and secure without overtightening, then drain and refill the machine to clear residual salt water. After a refill, the low-salt indicator may stay on for up to three complete wash cycles. Start a wash after filling so any spilled salt is rinsed off.

Common faults and simple checks

If the display shows an error, photograph it and call us. The official user manual says a red status indicator means a serious error, and the stage display shows the error number. Its troubleshooting section mentions E12 and E13 in connection with fill and water-supply problems, and E16 with over-filling or overflow. It does not publish a full chef-facing code table, so we have not invented one, and we have not copied the earlier C400, C500, D500 and P500 table onto this page. Those older machines are covered on our Classeq error codes page; we have not confirmed that those meanings apply to the CP500 generation.

The official first step, if the machine has gone into error mode, is to switch the mains power off and on, then try the checks in the manual before requesting a service visit. These are safe checks a chef can try. Only do them if it is safe. Switch off and let the machine cool before you handle arms or filters. Leave the panels on.

• Confirm the machine is switched on at the wall and the water supply is fully on, and that the inlet hose is not kinked or trapped.
• Check the hood closes fully. The official manual lists an open hood as a reason the machine may not fill or start.
• Give the machine time to finish filling and heating if the status indicator is still flashing amber — that can take around 30 to 40 minutes from cold, depending on the supply and incoming water temperature.
• Remove, clean and refit the wash arms and the primary and secondary filters.
• Check the waste hose is not kinked or blocked, and that the site drain is clear. If the machine is over-filling, the official manual says to try a drain-down; if it will not drain, stop the machine and check the site drains, then call us if it continues.
• On machines with built-in water treatment, check the water-treatment salt reservoir is not empty.
• Check detergent and rinse-aid bottles, weights and tubes if wash results are poor or there is excessive foam.

If water is near electrics or you smell burning, switch off at the wall or isolator if it is safe, turn off the water, and call us.

When to call a technician

• An error comes back after the safe checks, or the display stays red.
• The machine will not fill, drain, heat or start once power, water and hoses have been checked.
• There is a leak, overflow, burning smell or tripping power.
• Wash results stay poor after cleaning, pre-rinse and a chemical-supplier check.
• You need help with installation, chemical dosing or water treatment.
• The display shows a service reminder, or the machine is due for a service.

You get an electronic service report, with electrical certification as required. Our work is covered by a 90-day parts and labour warranty. A dishwasher hygiene check starts from $140 + GST, depending on the model, and a full dishwasher service including a hygiene check starts from $220 + GST.

We service and repair Classeq dishwashers across Greater Wellington, the Kāpiti Coast, the Wairarapa and Manawatū. See also commercial dishwasher repairs and the Dishwasher Hygiene Check.

FAQ

Where is the official Classeq CP500 manual?

Classeq Pty Ltd publishes a public Pass-through Warewasher User Manual (document 90002093, Revision D) covering the CP500, CP500-WS, CP500-AS and the steam-recovery (SR) variants of those models. Official product pages, an Australian specification sheet, and Classeq’s June 2025 product brochure and product guide are also public. The UK download centre still needs a login for some files. This CES Wellington page is a short kitchen-facing guide only. It is not a copy of those documents.

What is a Classeq CP500?

The CP500 is Classeq’s current pass-through, or hood-type, warewasher. Classeq Australia describes it as a High Volume Pass Through Dishwasher Or Glasswasher. It can be commissioned as a dishwasher or a glasswasher, and set up for a straight-through or corner location. It is not the older P500, and it is not the undercounter D500. Factory options include built-in water treatment (WS), a twin rinse element (AS), and a steam recovery unit, sold in Australia as the CP500SR.

What programmes and temperatures does the CP500 use?

The official user manual’s factory settings are: as a dishwasher, Light 1.5 minutes, Standard 3 minutes, Intensive 5 minutes and Utensil 7 minutes, with a 60°C wash and 82°C rinse (the utensil programme shows 62°C wash and 85°C rinse). As a glasswasher, Light 1.5 minutes and Standard 2 minutes, with a 60°C wash and 70°C rinse. A heat interlock can extend the cycle if the rinse is not up to temperature. Confirm the mode on the rating plate and display.

Does every CP500 have steam recovery or built-in water treatment?

No. Steam recovery is a separate SR variant, not a standard feature of the CP500. See our CP500SR manual and quick guide. Built-in water treatment is the WS option. Standard machines need an external water-treatment solution if the site water requires it.

What does an error on a CP500 mean?

Photograph the display and call us. The official user manual shows a red status indicator and an error number on the display. Its troubleshooting section mentions E12 and E13 in connection with fill and water-supply problems, and E16 with over-filling or overflow. It does not publish a full chef-facing code table, so we have not invented one. Our Classeq error-codes page covers earlier C400, C500, D500 and P500 machines and may not match this generation.

How quickly can you come out?

We offer same-day response, and a 2-hour emergency response target, depending on workload. Calls are answered 24 hours, 7 days on 0800 90 60 30.
