Washer or Dishwasher Not Draining? You Might Have a Pump Issue

When the Pump Stops Working, the Appliance Stops Too

The pump is one of the most critical components in your washer or dishwasher. It is responsible for moving water either through the machine or out of it. When a pump issue occurs, the appliance may not drain, the cycle may freeze, or you might hear strange noises from inside the unit. Swift Appliance Repair often sees these cases with both residential and commercial machines. A faulty pump can leave your appliance full of water and completely inoperable.

Common Warning Signs of a Pump Problem

Most homeowners first notice a pump issue when the appliance refuses to drain. But there are other indicators worth paying attention to:

• Standing water: After a cycle, water remains at the bottom of the drum or tub.
• Cycle interruption: The machine stops mid-cycle and does not move forward.
• Humming sound: The appliance makes a low buzzing noise, but nothing happens.
• Loud rattling or vibration: Mechanical parts inside the pump may be damaged or blocked.
• Error codes: Modern appliances may display a drain or pump error such as E20, F21, or OE depending on the brand.
• Water left after power reset: Even after unplugging and restarting, the machine still holds water inside.

What Causes a Pump to Malfunction?

A pump issue is rarely caused by just one thing. Our technicians have found that the following problems are most often responsible:

• Debris or blockages: Small objects, lint, food particles, or even hair can clog the filter or pump impeller.
• Worn pump components: Internal parts can wear out over time, especially in high-usage machines.
• Electrical faults: Corroded wires or broken connections prevent the pump from receiving power.
• Damaged drain hose: A kinked or crushed hose will block water flow and overload the pump.
• Control board malfunction: The system may fail to send the signal that activates the pump at the correct time.

Each of these issues requires a different approach. Without proper tools and expertise, it is difficult to determine the real cause.

Appliances Commonly Affected

While pump problems are most often seen in washing machines, they are not exclusive to them. Swift Appliance Repair regularly handles pump-related failures in the following equipment:

• Washing machines: Drain pumps are essential to remove water after each cycle.
• Dishwashers: Use both circulation and drain pumps to operate efficiently.
• Dryers with steam or condensation systems: May include small pumps to remove condensed moisture.
• Other appliances: Coffee machines, portable air conditioners, and water heaters may also rely on pumps for internal circulation.

Why Professional Repair Is the Smart Choice

Although a pump issue may seem straightforward, attempting to fix it without proper training can make the problem worse. The components involved are often located deep within the machine and may require disassembly, electrical testing, or full replacement. Incorrect handling can lead to leaks, further damage, or safety hazards. That is why we recommend contacting a qualified technician.
