Retained water can involve the filter, drain path or a pump obstruction. Save the program and message, then use only the owner checks described for your exact model.
What to note before calling
| What you notice | Useful next step |
|---|---|
| Water remains inside | Note when the program stopped and whether a message was shown. |
| A leak is visible outside | Stop the appliance and protect the area. A floor leak and retained tub water are different observations. |
| Plumbing work happened recently | Include that history, without assuming it proves an appliance or installation fault. |
The drain path includes more than the pump
Thermador identifies a dirty filter, blocked drain lines and debris at the pump as possible reasons water remains. Its guidance also makes installation relevant. Follow the exact manual for an owner-accessible filter; do not improvise pump removal or hose work. This is why a drain complaint after sink work should include that history before a pump is ordered.
Use the owner guidance for the installed model
Use Thermador’s documentation for the full model identifier on the appliance. Filter and pump access instructions can vary. This guide does not provide a universal pump-removal sequence or interpret an error code without the matching manual.
Tell retained water apart from wet dishes
A completed program that leaves dishes wet is not the same report as water retained in the tub after an interruption. Record the selected program, whether it finished and any message. Recent work under the sink is relevant history, but it does not establish responsibility for the condition.
When to stop owner checks
Do not keep rerunning the program when it is malfunctioning. Avoid reaching into hidden pump components, opening electrical covers or pulling the dishwasher from its installation. Ask about the exact model and appropriate service before going beyond the owner guide.
A FEW HELPFUL ANSWERS
Before your service visit
Should I buy a drain pump if water remains in the dishwasher?
No. Retained water does not establish a failed pump. The cycle history, installation, error information and appliance need assessment before a part or repair can be recommended.
Can the model of a similar-looking dishwasher identify the error?
Use the installed dishwasher’s full identifier, including any suffix shown. Similar controls do not establish that error meanings or owner-access procedures are identical.
