Miele Dishwasher Error Code F69

F69 indicates that the heater pressure switch is detecting insufficient water pressure while the circulation pump is running. This points to a blockage somewhere in the circulation system or a faulty pressure switch. The dishwasher stops operation to prevent damage to the pump and heating components. A technician will need to inspect for obstructions and potentially replace the heater pressure switch.

No, you should not continue running the dishwasher while F69 is active. The error indicates the circulation system is not functioning correctly, and continued operation could overheat or damage the pump motor and heating components. Leave the dishwasher off until the fault is diagnosed and repaired.

A reset may temporarily clear the fault display, but if the underlying blockage or defective pressure switch has not been addressed, the F69 code will return once the dishwasher attempts to run a cycle. A reset alone is not a repair and should only be used as part of a systematic diagnostic process, not as a solution.

Some steps, like removing and cleaning the dishwasher filters and checking for visible debris around the pump area, can be done by a careful DIYer. However, accessing and replacing the heater pressure switch requires disassembly of internal components and is best handled by a qualified technician. Attempting pump or switch work without proper knowledge of the dishwasher's internals carries a risk of causing additional damage.

Repair costs vary depending on the root cause. If only the heater pressure switch needs replacement, parts and labor typically range from around 100 to 250 dollars. If the circulation pump itself is damaged or blocked by debris requiring significant disassembly, costs can range from 200 to 450 dollars or more, depending on local labor rates and parts pricing.
