Winterhalter UC series
These Err codes are from the UC series service instructions. The UC operating instructions also show many of the same problems as pictograms, and say to contact a Winterhalter service technician if you cannot clear the fault yourself.
| Code | What it means | What you can safely do |
|---|---|---|
| Err 1 | Rinse aid container or built-in storage tank empty (a signal has been present for longer than 3 minutes). The dosing device switches off after 20 wash cycles. | Replace the rinse aid container or top up the storage tank if your machine has an empty indicator. If the code remains, call us. |
| Err 2 | Detergent container or built-in storage tank empty (a signal has been present for longer than 3 minutes). The dosing device switches off after 20 wash cycles. | Replace the detergent container or top up the storage tank if your machine has an empty indicator. If the code remains, call us. |
| Err 3 | Not enough top wash field rotations (fewer than 3 rotations in 20 seconds). The wash field is blocked. | Remove whatever is blocking the top wash field (for example tall dishes). If it comes back, call us. |
| Err 4 | Not enough bottom wash field rotations (fewer than 3 rotations in 20 seconds). The wash field is blocked. | Remove whatever is blocking the bottom wash field (for example a piece of cutlery). If it comes back, call us. |
| Err 5 | Lack of salt on machines with built-in water treatment, or the set water volume has been used on machines with a demineralisation cartridge. | On a machine with built-in water treatment, fill the container with water treatment salt as the manufacturer directs. If you have an external treatment unit, it may need replacing — call us if you are unsure. |
| Err 6 | Door is open, or the door reed switch is defective, while the machine is filling, washing or self-cleaning. | Close the door fully. If the code remains with the door closed, call us. |
| Err 7 | Tank does not fill within a specified time. The machine switches off automatically. | Open the water stop cock, and clean the dirt filter in the dirt trap if it is safe to do so. If it comes back, call us. Leave the panels on. |
| Err 8 | Boiler does not fill within a specified time (600 seconds). | Open the water stop cock, and clean the dirt filter in the dirt trap if it is safe to do so. If it comes back, call us. Leave the panels on. |
| Err 10 | The set number of operating hours or wash cycles for the service counter has been reached. | Call us to arrange a service. |
| Err 11 | Tank level is too low during washing (dry running protection). The strainer is clogged. The error is displayed until the door is opened once. | Remove, clean and refit the strainer. Opening the door once clears the display. If it comes back, call us. |
| Err 15 | The set number of operating hours for the descaling indicator has been reached. | The machine may need descaling. Call us if you want us to do that work. |

Winterhalter PT series
PT pass-through machines (including PT-500) use E-codes from the same controller family as Classeq P500. The PT-500 operating instructions also show pictograms and say that a malfunction with an error code should be read and then referred to a technician if you cannot clear it.

Safe checks to try first
- Door or hood: closed fully.
- Water supply: the stop cock is open, and the dirt filter in the dirt trap is clean.
- Chemicals: detergent and rinse aid are not empty.
- Wash fields: top and bottom arms are free to turn and not blocked.
- Strainer: removed, cleaned and refitted.
Leave the panels on. There are live electrical parts inside. If you see water near electrics or smell burning, switch off at the wall or isolator if it is safe to do so, and call us.
When to call a technician
- The safe checks above do not clear the code.
- The code is a sensor, heating, communication or over-temperature fault.
- There is a leak, a burning smell, or tripping power.
A Dishwasher Hygiene Check starts from $140 + GST, depending on the model. A full dishwasher service, including a hygiene check, starts from $220 + GST.
FAQ
What does Err 1 mean on a Winterhalter UC dishwasher?
Err 1 means the rinse aid container or built-in storage tank is empty. Replace or top up the rinse aid if your machine has an empty indicator. If the code remains, call 0800 90 60 30.
What does Err 7 or Err 8 mean on a Winterhalter UC?
Err 7 means the tank did not fill in time, and the machine switches off. Err 8 means the boiler did not fill within 600 seconds. Open the water stop cock and clean the dirt filter if it is safe. If it comes back, call us.
What does Err 11 mean on a Winterhalter UC?
Err 11 means the tank level is too low during washing (dry running protection), usually because the strainer is clogged. Clean and refit the strainer. The error stays on the display until the door is opened once.
Are Winterhalter UC and PT error codes the same?
No. UC undercounter machines use Err 1, Err 2 and so on. PT pass-through machines use E01, E03, E07 and the same family of codes as Classeq P500. Use the section that matches your machine.
What does E07 mean on a Winterhalter PT?
On a PT series machine, E07 means the rinse tank has not reached its target temperature within 60 minutes. Call a technician and leave the panels on.
The display shows a picture, not a number. What should I do?
UC and PT operator manuals also use pictograms for door open, empty chemicals, water shortage, blocked wash fields and a blocked strainer. Try the matching safe check on this page. For a numeric code, photograph the display and call 0800 90 60 30.
