Thermador Dishwasher E0106 Points to the Wash Arm Diverter

What E0106 means

The wash seems to favor one rack, and E0106 appears. Thermador documents this code as a problem in the wash arm diverter circuit. The diverter is what sends water between the spray arms, and the control found its drive circuit not responding as expected when it tried to switch. Because the display shows only a number, the way the racks come out is often the best clue we get before a visit.

Usual causes of E0106

A failed diverter motor, or a failed circuit that directs water between the spray arms

✓ A safe check worth trying

1. Switch off the dishwasher's breaker. 2. Wait thirty seconds, then restore power. 3. Run a short cycle and check whether the display clears. 4. After the cycle, look at the lower and upper racks and note which one came out cleaner, then pass that along when you call.

! Why you should stop here

The diverter lives inside the wash system and cannot reasonably be reached for a DIY repair.
Even if the cycle finishes, unevenly washed racks will continue until the diverter is repaired.

Taking off a panel yourself does not by default void a manufacturer warranty, yet it can lead to accidental damage, and some manufacturers attach their own service terms. Read your warranty paperwork, or ask us, before you decide.

E0106E0106 questions

Could this be why one rack washes better than the other?

Yes. If the diverter cannot move, one spray arm may get most of the water, and dishes in the other rack come out dirtier. We then confirm it on site, with a written price first.

Is it safe to keep running cycles?

The code is not a safety shutdown, but each cycle may waste detergent and water on poor results. Stopping until it is checked saves rewashing.

Will the visit involve taking the machine apart?

Likely some disassembly, since the diverter is inside the wash system. We report our findings and put the price on paper before any parts go in.
