Bosch dishwasher was does code ho1 mean? - Bosch Dishwashers

SOURCE: What does error code 01 mean on my bosch silence plus 42 dishwasher mean?

The 01 error code means that the incoming water isn't coming fast enough. This could be a problem with the water pressure in the building, the fill valve or the water flow meter. Sometimes, this can be caused by something blocking the float from moving freely inside the dishwasher tub.

First check that you have sufficient water pressure in the house and that the shut-off valve is fully open. (If you have low water pressure, find out what is causing the issue.) Make sure that the incoming water pipe/hose isn't crimped or leaking. Next, flip your circuit breaker to off (or unplug the unit) to reset the dishwasher. Next you need to check that the fill valve is opening and closing properly; check that the wiring is good as well. If that is fine, then the problem is the flow meter or the circuit board that reads the sensors from the fill valve and flow meter.

I hope this helps.
