the emitter.

Drain Pump

This dishwasher contains an independent drain pump. It is of a wet rotor design to prevent leaks. The

drain pump is mounted directly to the rear of the sump. The pump cover can be removed for cleaning.

The discharge end of the pump has a check valve to prevent water and odors from entering the

dishwasher from the house drain system. The intake of the pump is connected to the sump by a short

connecting hose. The pump is delivered as a complete assembly.

Checking the Drain Pump

A service test can be performed to test all functions of the dishwasher, including the drain pump.

• The service test is covered in section “Component Function Test”.

IF THE DRAIN PUMP DOES NOT OPERATE

Disconnect dishwasher from power supply.

The location of the drain pump requires that you check the circuit at the control.

• Check between P3-6 brown and P3-8 white.

The resistance should read 26 ohms.
