Question about Dishwashers
The drain hose connects to the pump and runs to the sink drain (or to the air gap on top of the sink). The pump has a second hose that recirculates the water back into the dishwasher. The drain hose is roughly 1 1/2 inches in diameter. While inspecting the drain hose, check the recirculation hose as well.If checking for blockages, disconnect the drain hose from the pump, pinch the wire clamp with pliers and slide it up the hose. Place a shallow pan beneath the pump to catch any spillage. Remove the hose from the pump; wiggling the hose may help to loosen it
The drain valve is typically near the motor although it can be located elsewhere. Look for a water hose running from the motor or underside of the tub. The hose should lead to the drain valve. The valve consists of the the gate arm mechanism and a solenoid (also called a coil). The gate arm allows the water to flow out of the dishwasher's tub through the drain valve. You should be able to move the gate arm up and down easily and smoothly. The gate arm also has two springs attached to it. If either of the springs is missing or damaged, they should be replaced.
The gate arm mechanism is engaged by the drain valve solenoid. The solenoid is connected by two wires. Label the wire placement on the solenoid before disconnecting the wires. The wires are connected with slip on connectors. Firmly pull the connector off of the solenoid's terminals (do not pull on the wire). You may need to use a pair of needle-nose pliers to remove the connectors. Inspect the connectors and the terminals for corrosion. If the connectors are corroded they should be replaced
