Bosch Dishwasher Repair – North Canton, OH (SHP78CM4N/25)

A Bosch dishwasher on Macnaughten St NW in North Canton was showing error code E9240 even after reboot. Three consecutive stored fault codes confirmed a slow drain condition caused by a missing drain hose high loop and debris in the drain path.

The Problem

The customer reported error code E9240 even after reboot of dw. This persistent fault code indicated an ongoing issue that wouldn’t clear with a simple restart.

Diagnosis

Three consecutive stored E:9240 fault codes were retrieved via the CS test program confirming a slow drain / water in sump condition. Root cause was identified as a missing drain hose high loop allowing water to siphon back into the sump between cycles, with additional drain path debris contributing. BSH Techline was consulted and confirmed the diagnosis, noting that if the condition persists the next recommended step would be drain pump replacement due to reduced pumping efficiency.

The Repair

• Parts replaced: No parts replaced
• Work performed: Installing a proper high loop per BSH installation specifications and clearing the drain path
• Result: Full CS test program was run to completion with no fault codes generated and drain pump pumping clear on all drain cycles

Is It Worth Repairing?

This Bosch dishwasher received a no-cost repair that addressed the root cause of the drainage issue. Bosch builds quality appliances, and proper installation details like drain hose high loops are critical for long-term reliability. This unit should provide years of continued service with the drainage system now functioning correctly.

Maintenance Tips for Bosch Dishwashers

• Run Bosch dishwasher cleaner monthly to prevent buildup in the wash arms and drain system
