Thermador Dishwasher Not Draining (E24, E25)
Thermador’s support pages tie E24 to a blocked drain filter or a drain pump cover that has come loose, and E25 to a blocked pump or a jammed impeller. In practice that’s usually glass, a label or fruit seeds caught at the pump, or a drain hose kinked behind the cabinet.

Problems we fix most
- Water left in the bottom after the cycle
- E24 or E25 on the display
- Cycle stopping partway with a drain fault
- Humming or gurgling but no draining
- Water backing up from the garbage disposal
Error codes we see
Just had a garbage disposal installed? Thermador points out that a disposal’s knock-out plug left in place stops the dishwasher draining.
How we diagnose a Thermador that won’t drain
We clean the filter set and the pump chamber, check that the pump cover is seated, then test the drain pump and follow the hose to the sink connection or the disposal.
Thermador Leak Protection Shut-Off (E15)
E15 means the safety switch has found water in the base and the leak protection has stopped the dishwasher. Thermador’s advice is to turn off the water supply first. Drying out the base clears the code for a while, but it returns unless the leak itself is repaired.
Problems we fix most
- E15 and the dishwasher won’t run
- Water on the floor in front of the door
- Drips from the corners of the door
- Foam overflowing after hand-dish soap was used
- E15 back again a few days after it cleared
Before you book
Turn off the water and the power to the dishwasher, and don’t run it again until the leak has been found. Note the model number from the edge of the door.
How we find a Thermador leak
We trace where the water in the base came from (a hose, the door seal, the sump gasket or a pump seal), repair it, then dry the base and reset the float switch. The inlet hose and valve get checked as well, since a slow drip there trips the same sensor.
Thermador Drying & Cleaning Problems
Sapphire models dry with StarDry, which uses zeolite, a mineral that draws moisture out of the air during the cycle, and wash with a ZoneControl spray arm. The zeolite isn’t a part that wears out, so when dishes come out wet or dirty, the cause is usually heating, a blocked spray arm or the filter.

Problems we fix most
- Dishes wet at the end of the cycle
- Glasses cloudy or spotted
- Food left on the top rack
- Water not hot during the wash
- Cycles much longer than they used to be
Worth checking first
Clean the filter, make sure nothing blocks the spray arms, and check the rinse aid level. If dishes are still wet or dirty, book a visit.
How we diagnose drying and cleaning problems
We measure the water temperature and test the heater, then check the circulation pump and the spray arms for blockages. On StarDry models, drying complaints get a heating and airflow check before we look at rinse aid or how the racks are loaded.
Thermador Door, Panel & Noise Repairs
On a custom panel-ready Thermador, the door carries the weight of your cabinet panel, so its springs have to match that weight. A door that drops open or slams shut usually needs its springs and cables set again. And with the Star Sapphire rated at 42 dBA, a new grind or hum is easy to hear; it usually comes from a pump.

Problems we fix most
- Door dropping open or slamming shut
- Door won’t latch, or the cycle won’t start
- Grinding or humming during the wash
- Panel sitting crooked against the cabinets
- Sapphire Glow light not coming on
What to tell us
Whether the dishwasher has a custom panel, when the noise happens (filling, washing or draining), and any code on the display.
How we diagnose door and noise problems
We set the door springs and cables to suit the panel’s weight, check the latch and its switch, then listen through a cycle to find which pump is making the noise.
Repair or replace a Thermador dishwasher?
Repair it in most cases. A Star Sapphire retails for around US$2,499 before its custom panel and installation, while most of the faults on this page come down to a pump, a seal, a door spring kit or a sensor. A repair also keeps your custom panel on the door it was made for.
| What it involves | Repair | Replace |
|---|---|---|
| The dishwasher | Your Thermador stays | A new Star Sapphire retails around US$2,499, a Sapphire around US$1,999 |
| Custom panel and handle | Stay on the door | A new model may need a new or re-cut panel and handle |
| Installation | One technician visit | Water, drain and power connections, fixing to the counter, door spring set-up |
| The old unit | Nothing to dispose of | Haul-away and recycling |

Thermador repair questions
What does E15 mean on a Thermador dishwasher?
Water has reached the base and the leak protection has stopped the machine. Turn off the water supply and book a visit: we find and repair the leak before drying the base and resetting the switch.
What do E24 and E25 mean?
Both are drain faults. Thermador links E24 to a blocked drain filter or a loose pump cover, and E25 to a blocked drain pump or a jammed impeller. We clean the drain path and test the pump.
Why are my dishes wet in a Sapphire dishwasher?
StarDry needs a properly heated wash and clear airflow, so a weak heater, a blocked filter or low rinse aid can all leave dishes wet. We check the heating first.
Do you repair custom panel-ready Thermador dishwashers?
Yes. We protect the panel while the dishwasher is out and set the door springs to suit its weight when it goes back in.
Do you repair Star Sapphire and Emerald models?
Yes, as well as Sapphire. The repairs we do most are the same across all three: drain codes, leak shut-offs, drying problems and noise.
Is it worth repairing a Thermador dishwasher?
In most cases. A Star Sapphire retails for around US$2,499 before its panel and installation, and most faults come down to a pump, a seal, a door spring kit or a sensor.
What does E22 mean on a Thermador dishwasher?
Thermador lists E22 as a blocked filter. Take the filter out, rinse it under running water with a soft brush and refit it. If the code comes back, book a visit.
Should I call Thermador first?
If the dishwasher is still under Thermador's warranty, call Thermador first so the repair is covered. Out of warranty, book with us and we can usually diagnose it the same day.*
