Bosch Dishwasher Error Code Check water supply

It means the dishwasher started a programme but did not detect water entering the tub within the expected timeframe. The machine stops the cycle and sounds a continuous beeping alert to prevent the pump and heater from running without water. The issue can range from a simple closed tap to a blocked hose, a clogged filter screen, or a faulty inlet valve or Aquastop assembly.

A reset alone will not clear the error if the underlying supply problem has not been resolved first. The alert will return as soon as the machine attempts to fill and again fails to draw water. You need to correct the water supply issue, then use the M/OK button to resume the cycle, or restart the programme after addressing the root cause.

If the fix is simply opening a tap or clearing a blocked filter screen, there is no parts cost involved. Replacing an Aquastop hose assembly typically costs in the range of $30 to $80 for the part. A new water inlet solenoid valve generally falls in the $25 to $75 range for parts, with additional labor costs of $75 to $150 or more if a technician performs the repair.

Start by locating the mains water tap connected to the dishwasher and confirming it is turned fully open. Once the tap is open, press the M/OK button and close the door to allow the programme to resume. If the error persists, inspect the inlet hose for kinks, check the filter screen at the valve connection for blockages, and examine the Aquastop hose assembly if your model has one.

The dishwasher is designed to halt the programme when this error occurs, which protects the pump and heating element from running dry. You should not attempt to bypass the alert or force the machine to continue without resolving the water supply issue, as running the pump without water can cause significant internal damage.
