Question about Frigidaire 24 in. FDB635RF Built-in Dishwasher
HI. check the following areas for faults.
1. Air gap / Drain hoses
If there is an air gap (located in the sink, near the faucet), check to see if it is clogged. Unscrew the top cap and see if there is anything blocking inside. Note: If there is no air gap installed, the dishwasher might not drain properly.
If the drain hose is clogged, the dishwasher will not drain. If there is an air gap installed, it is very common that a hose going from the air gap into the garbage disposer is clogged. Remove and clean the hose. Make sure to reattach the hose before starting the dishwasher.
Note: If you recently had a garbage disposer installed, it is common to overlook removing the drain plug.
2. Broken belt
Some dishwasher models use a belt to drive the pump. Replace the belt if found broken.
Note: Sometimes the belt would just come off the pump. Even though it might not be broken, it is recommended that you replace the belt, because it is probably too stretched out.
Some models have two impellers inside the pump - one, wash impeller, takes care of the wash cycles, the other, drain impeller, drains the water out. If the drain impeller is broken (broken blades, shaft), the dishwasher would not drain. Replace any broken pump components.
4. Drain solenoid
Some models (for example most GE dishwashers) use a drain solenoid to drain water out. Sometimes the solenoid gets stuck, preventing the water from draining out. Try to free up the solenoid. If unsuccessful, you might have to replace the pump assembly.
If the motor is stuck, it is sometimes possible to free it up by manually spinning the motor.
Replace the motor if defective.
6. Control sector(This could be a timer module or control board)
Replace if defective (note: uncommon problem).
IF EQUIPPED, Check the drain solenoid.(Please disregard if your unit is not equipped with a drain valve)
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.
Test the solenoid for resistance using a multimeter. Set the multimeter to the ohms setting X1. Place a probe on each terminal. The multimeter should change from a reading of infinity to roughly 40 ohms when the probes touch the terminals. If the reading is infinity or substantially different from 40 ohms, the solenoid should be replaced asap.
