Error Code: E0105 Difficulty: Hard
Problem: Wash arm diverter circuit in main control board fault/error.
How to Fix E0105 Error (Step-by-Step)
- Disconnect the dishwasher from power by turning off the circuit breaker and unplugging the unit. Shut off the water supply valve, typically located under the sink.
- Carefully slide the dishwasher out from under the counter. You may need to remove mounting screws securing it to the countertop or cabinets.
- Lay the dishwasher on its back on a towel or blanket to access the base. Remove the base cover panel to expose the internal components.
- Locate the Zeolite container, which houses the heater. Disconnect the wiring harness attached to it and any connected hoses. Release the clips or screws holding it in place and remove the old container.
- Install the new Zeolite heater and container assembly, ensuring all connections are secure. Reconnect the wiring harness and hoses.
- Locate the main power module (control board). Carefully label and disconnect all wire connectors. Remove the screws securing the module and replace it with the new one, reconnecting all wires to their correct terminals.
- Reassemble the dishwasher by reattaching the base panel, sliding it back into place, securing it, and reconnecting the power and water supply. Run a test cycle to confirm the repair.
- Turn the appliance off, wait about 2 minutes, then turn it back on.

What to Check Next on This Bosch Dishwasher
Bosch dishwasher symptom: Use the symbol or code as a starting point, then match the repair path to what the dishwasher is actually doing.
- Confirm whether the display is a normal cycle/status symbol or a recurring fault that stops operation.
- Check water supply, filter, sump, spray arms, drain path, and door latch before replacing electronic parts.
- If the same problem returns after basic checks, inspect the matching sensor, pump, heater, wiring, or control path based on the symptom.
If the symptom returns after these checks, use the full Bosch model number from the door tag before ordering any part. The same display message can point to different parts depending on the exact model and what the dishwasher does during fill, wash, drain, or dry.
