A malfunctioning dishwasher can be a major inconvenience, especially when it refuses to drain. If you’re facing this issue with your Frigidaire dishwasher, understanding the underlying causes is crucial. This comprehensive guide will delve into the potential reasons why your dishwasher won’t drain, empowering you to troubleshoot and resolve the problem effectively.
Potential Causes and Fixes
1. Clogged Drain Hose
- Cause: Food particles, grease, and other debris can accumulate in the drain hose, obstructing water flow.
- Fix: Disconnect the drain hose from the sink or disposal and inspect it for blockages. Clear any clogs using a plumber’s snake or a wet/dry vacuum.
2. Faulty Drain Pump
- Cause: The drain pump is responsible for expelling water from the dishwasher. A malfunctioning pump can prevent drainage.
- Fix: Test the drain pump by pouring a gallon of water into the dishwasher. If the water doesn’t drain, replace the pump.
3. Blocked Air Gap
- Cause: The air gap is a small device that prevents water from siphoning back into the dishwasher. If it becomes clogged, it can impede drainage.
- Fix: Locate the air gap under the sink and remove any debris or blockages. Ensure the drain hose is properly connected to the air gap.
4. Kinked Drain Hose
- Cause: If the drain hose is kinked or bent, water flow can be restricted.
- Fix: Inspect the drain hose for any kinks or bends. Straighten it out and ensure it’s not crushed or obstructed by other appliances.
5. Faulty Dishwasher Switch
- Cause: The dishwasher switch activates the drain pump. A faulty switch can prevent the pump from operating.
- Fix: Test the switch using a multimeter. If it’s not functioning properly, replace it.
6. Malfunctioning Control Board
- Cause: The control board is the “brain” of the dishwasher and controls various functions, including drainage. A malfunctioning control board can disrupt the drain cycle.
- Fix: Diagnosing and repairing a faulty control board is complex and requires professional expertise. Contact a qualified appliance technician.
7. Clogged Sump Filter
- Cause: The sump filter traps food debris and prevents it from entering the drain pump. If it becomes clogged, it can restrict water flow.
- Fix: Locate the sump filter at the bottom of the dishwasher and remove it. Clean it thoroughly under running water and reinstall it.
