Frigidaire Professional Dishwasher: Detergent Pod Not... | appliancefaults.com

Technical Background:

The dishwasher's Main Control Unit (MCU) controls the water fill valve, wash pump motor, dispenser solenoid, and heating element. Voltage is supplied to these components based on the selected cycle and sensor feedback. A malfunctioning component or sensor can disrupt the wash cycle and prevent the detergent from dissolving correctly.

Symptoms:

The detergent pod remains intact in the dispenser after the dishwasher cycle, dishes are not clean, and there might be residue on the dishes.

Possible Causes:

Low water temperature
Clogged spray arms
Weak or failing wash pump
Dispenser door malfunction
Using the wrong type of detergent or too much
Low water pressure to the dishwasher

Solution:

1

Verify the hot water supply. Use a thermometer to ensure the water entering the dishwasher is at least 120°F at the faucet closest to the dishwasher.
2

Inspect and clean the spray arms. Remove the upper and lower spray arms and check for clogs. Use a small wire or toothpick to clear any obstructions. Ensure the arms rotate freely.
3

Test the wash pump motor. Disconnect power to the dishwasher at the breaker. Access the wash pump and use a multimeter to check for continuity. Replace the pump if there is no continuity or the windings are open.
4

Examine the dispenser door mechanism. Manually cycle the dispenser door and check for smooth operation. Test the dispenser solenoid for 120V AC during the dispenser activation phase of the cycle with a multimeter.
5

Ensure proper detergent usage. Use only dishwasher-specific detergent pods and avoid overloading the dispenser.
6

Verify adequate water pressure. Check the water pressure at the dishwasher inlet valve. It should be at least 20 PSI. A plumber may be needed to increase house water pressure.
7

Inspect the drain hose. Check for kinks or obstructions that may be preventing proper drainage and water circulation.

Safety Warning:

Disconnect power to the dishwasher at the breaker panel before performing any repairs. Lock Out/Tag Out (LOTO) procedures should be followed to prevent accidental energization. Be aware of high voltage present when testing components. Use appropriate safety equipment, including insulated gloves.

Prevention:

Run the hot water faucet before starting the dishwasher to ensure hot water enters immediately. Regularly clean the spray arms and filter to prevent clogs. Use a dishwasher cleaner monthly to remove buildup.

Expert Tip:

Run the dishwasher through a full diagnostic cycle to identify any error codes stored in the MCU. Consult the service manual for the specific procedure for your model. Often, holding down two buttons simultaneously for 3 seconds initiates the service mode.

Frequently Asked Questions

Typically, you need to remove the lower spray arm, filter assembly, and any lower racks. Then, you should be able to access the pump from inside the dishwasher tub. Some models may require removing the dishwasher from under the counter for access from underneath.

•What type of multimeter is best for testing dishwasher components?

A digital multimeter (DMM) that can measure AC and DC voltage, resistance (ohms), and continuity is recommended. Make sure it's CAT III rated for safety.

•Where can I find the service manual for my Frigidaire Professional dishwasher?

You can often find it online by searching for the model number followed by 'service manual'. Sites like AppliancePartsPros or RepairClinic often have them. Alternatively, you can contact Frigidaire directly.
