CES Wellington services and repairs Classeq D500 dishwashers 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: Duo and built-in water-treatment variants differ from the standard D500.

Official Classeq manuals

These official Classeq documents are still published on classeq.co.uk and cover the D500:

Undercounter dishwasher and glasswasher Quick User Guide (document 30014478, Revision A), which lists the D500, D500 Duo and D500 Duo WS
The Classeq product guide (July 2022), which includes the D500 specification table

Classeq’s full user and installation manuals sit in its download centre, which needs a login. Classeq’s current live undercounter range on the same site is the C400, C500 and C500 Utensil. The older D500 product page path no longer resolves, so this guide links the documents that still do.

Key specs (standard D500)

These figures are from Classeq’s July 2022 product guide for the standard D500. Confirm them against the rating plate and the official documents for the machine on site.

Front-loading undercounter dishwasher with a 500 mm basket, holding 18 ten-inch plates, and 343 mm plate clearance.
Cabinet size 550 mm wide, 605 mm deep and 830 mm high.
Three wash programmes of 2, 3 and 5 minutes. Theoretical capacity of 30 racks an hour, and up to 540 dinner plates an hour based on an optimal set-up.
Colour-coded LCD display showing wash and rinse temperatures, and simple two-button control.
Auto dosing fitted as standard.
Gravity drain as standard, with a drain pump available as an option (the D500 Duo includes a drain pump and a rinse booster).

The D500 Duo is listed separately in the same guide: 570 mm wide, 605 mm deep and 830 mm high, with a drain pump and rinse booster included, WRAS type AB, and optional built-in water treatment. Do not treat Duo figures as the standard D500.

Installation and water requirements

Installation should be carried out by a suitably qualified person, following Classeq’s Installation and Operation manual for the machine. The engineers’ manual for this undercounter family points installers to that document for dimensions and site requirements; we have not copied installer-only procedures here.

The official product guide lists a required water pressure of 2.0 bar for the standard D500. On that standard machine, rinse performance depends on the site water pressure. Duo models are listed at 0.5 bar, or 2.0 bar when built-in water treatment is fitted. We have not published other inlet, flow or electrical figures here, because we could not confirm them in a currently available official public document.

On water treatment, the same guide is clear: the standard D500 is not supplied with built-in water treatment and needs an external water-treatment solution. Built-in water treatment is optional on the D500 Duo. For options we install and service, see commercial water filters and Kitchen Talk on water treatment.

Daily use, cleaning and end of shift

The official Quick User Guide is meant to be used after the machine has been commissioned. In outline it says: press On — the button flashes amber while the machine fills and heats; when it is ready the Start button turns green and the cycle can run. If you do not want the default programme, use Select until the display shows the cycle you need; a blue cycle indicator confirms the selection. Rinse loose debris off items before you load them, then close the door. See the official guide and the full user manual for loading detail.

Clean the interior after each service, once the machine has been drained. The official Quick User Guide asks you to remove and clean:

the top and bottom wash and rinse arms
the primary filters
the secondary filters
the wash tank, including apertures and outlets, with a sponge or brush

It also says to clean around the door hinge, and, on pumped-drain machines, to rinse the ball in the anti-syphon device with a trigger spray. Food-grade grease can be applied to the door ball catch if needed. Refit all arms and filters before you turn the machine back on. Leave the panels on — there are live electrical parts inside.

Chemicals and water treatment

Auto dosing is fitted as standard on the D500 range in the official product guide. If wash results are poor, or you are changing chemicals, consult your chemical supplier and, if needed, book a technician to check calibration.

If your machine has built-in water treatment, the official Quick User Guide shows a low-salt warning icon. It says the water-treatment salt should be replenished promptly to help avoid limescale. The official refill steps are: open the door, remove the right-hand basket ramp, take off the salt-reservoir cap at the back right of the wash chamber, fill the reservoir with granulated salt using the funnel supplied, wipe away any spilled salt, refit the cap so it sits flat and secure, then drain the machine to clear the salt water. Before first use, the reservoir should be filled with fresh water as the user manual’s commissioning section describes. Do not put detergent or rinse aid in the salt reservoir. This salt refill does not apply to a standard D500 with no built-in water treatment.

The official operator documents we have do not give a descaling recipe, so we have not invented one here. If you can see scale in the machine, or other equipment on the same supply already needs water treatment, get the incoming water checked. We can inspect the machine if you book a technician.

Common faults and simple checks

If the display shows an error code, photograph it and open our Classeq error codes page. That page covers the C400, C500, D500 and P500 controller family. If you see E15 or E25, call us. An engineers’ quick-reference guide lists titles for those two codes, but they are not in the engineers’ manual table, so this guide does not give a chef-facing meaning for them.

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 on, and that the inlet hose is not kinked.
Check the door opens and closes fully.
Remove, clean and refit the wash and rinse arms and the primary and secondary filters.
Check the waste hose is not kinked or blocked, and that the site drain is clear.
On machines with built-in water treatment, check the water-treatment salt reservoir is not empty.

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

When to call a technician

An error code comes back after the safe checks, or you see E15 or E25.
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 D500 manual?

Classeq still publishes a public undercounter Quick User Guide that covers the D500, D500 Duo and D500 Duo WS, and a 2022 product guide with D500 specifications. The full user and installation manuals are in Classeq’s download centre, which needs a login. This CES Wellington page is a short kitchen-facing guide only. It is not a copy of those documents.

What are the key specs of a standard Classeq D500?

Classeq’s July 2022 product guide lists the standard D500 as an undercounter dishwasher with a 500 mm basket holding 18 ten-inch plates, a plate clearance of 343 mm, and cabinet dimensions of 550 x 605 x 830 mm. It has three programmes of 2, 3 and 5 minutes, theoretical capacity of 30 racks an hour, and up to 540 dinner plates an hour based on an optimal set-up. Auto dosing is included. A drain pump is optional. Required water pressure is 2.0 bar. Confirm against the rating plate, because Duo and water-treatment variants differ.

Does every D500 have built-in water treatment?

No. The official product guide shows built-in water treatment as not fitted on the standard D500, and optional on the D500 Duo. Standard machines need an external water-treatment solution. If your machine has a salt reservoir and shows a low-salt warning, refill it with granulated water-treatment salt as the official Quick User Guide describes.

How should we clean a D500 at the end of the shift?

The official Quick User Guide says to clean the interior after each service once the machine has been drained. Remove and clean the top and bottom wash and rinse arms, the primary and secondary filters, and the wash tank, and clean around the door hinge. On pumped-drain machines, rinse the anti-syphon device as the guide shows. Refit the arms and filters before you turn the machine back on.

What does an error code on a D500 mean?

Photograph the display and see our Classeq error codes page, which covers the C400, C500, D500 and P500 controller family. If you see E15 or E25, call us — those two codes are listed in an engineers’ quick-reference guide but are not in the engineers’ manual table, so we do not give a chef-facing meaning for them here.

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.
