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

functions of the dishwasher, including the
drain pump.
- The service test is covered in section
“Test for the Control”.

· 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.
