3.9 Motor and Heater Plate Locknuts
There are two locknuts holding the heater plate and motor housing assembly into the base of the tub, these form a watertight seal by compressing the two seals.

The drain pump housing, which incorporates an inlet and outlet pipe, is welded to the motor housing, hence captivating the motor.
The inlet pipe plugs straight into the drain sump in the tub and is sealed there by a small ‘O’ ring.

The drain hose is an extruded blow moulded hose that is routed over the link assembly and exits out of the base of the product and is connected to a domestic drain.
The pump speed during the drain cycle is approx. 4200 rpm. In hardware output diagnostics test mode it is set to the same speed to aid diagnosing drain problems.
On a double product, the drain motor on the tub which is not being used will run for a short time during the final drain phase of a wash cycle. This is to remove any drain water that may have back flowed in to the unused tub.
This concurrent drain will not happen if the unused tub is open. If the user presses the power button after water has been placed in the tub, the product will initiate a “power off” drain and empty the tub.
