Error Code E26 Bosch

Symptom / Description

Error with the water switch (diverter valve). The wash cycle stops and dishes may not be clean.

Root Cause

The main control board is not receiving the correct feedback signal from the water switch, indicating it's not changing positions to direct water to the spray arms. This is likely due to faulty wiring, a defective switch motor, or a bad position sensor on the switch assembly.

Repair Instructions

UNLOCKED

Disconnect power. Access the water switch at the base of the unit. Inspect wiring and connectors. Test the switch and motor assembly with a multimeter for continuity and resistance. Replace the water switch assembly if it is found to be defective.
