Bosch Dishwasher Repair (Model HSU66CO6UC/43) – Alliance, OH

A Bosch dishwasher in Alliance was stuck in a continuous wash cycle and wouldn’t drain. We found a time delay issue that was preventing the control board from properly advancing through the wash program.

The Problem

The customer reported their Bosch dishwasher HSU66CO6UC/43 would start washing but never finish the cycle. It ran continuously without draining, leaving dishes sitting in dirty water. The unit appeared to be stuck in an endless loop, ignoring all attempts to reset or change cycles.

Diagnosis

We inspected the control board and found it was receiving proper power but had developed a time delay fault. This prevented the electronic control from properly timing the wash phases and advancing to the drain cycle. The control board was physically intact but the internal timing circuits had malfunctioned, causing the continuous operation without progression through the normal wash sequence.

The Repair

• Parts replaced: None required
• Work performed: Cleared the time delay fault and reset the control board timing circuits
• Result: Dishwasher completed a full test cycle with proper timing and drainage

Is It Worth Repairing?

This Bosch model is built to last, and control board timing issues like this are often resolvable without major parts replacement. Since the physical components were sound and only the timing circuits needed reset, this repair made good economic sense. Bosch dishwashers typically run 12-15 years with proper maintenance.

Maintenance Tips for Bosch Dishwashers

• Check the fine mesh filter at the bottom monthly — Bosch uses a 3-part filter system that captures food particles
• Run the Bosch “Machine Care” cycle monthly with their recommended cleaner to prevent mineral buildup on sensors
• Keep the door seals clean and inspect the spray arm holes for clogs — Bosch arms have small precision holes that block easily
