How to Replace Faulty Dishwasher Parts

dishwasher repairs

Are you having issues with your dishwasher not cleaning properly or making strange noises? Replacing faulty internal parts is likely the solution and easier to do yourself than you may think. With a few basic tools and safety precautions, you can have your dishwasher running like new again.

Assess the Issue

Before replacing parts, it’s important to properly diagnose the problem. Common dishwasher failures include:

Not cleaning dishes properly

    – Cause: Clogged or faulty wash arms, water inlet issues, weak drain pump, etc.

Leaking water

    – Cause: Damaged door seal, cracked tub, loose hose clamps, etc.

Unusual noises

    – Cause: Bad wash pump, broken fan blade, stuck utensils, etc.

Carefully listen, look inside, and test cycles. Be ready to replace the following common parts:

Dishwasher Spray Arms

Clogged or broken spray arms result in unclean dishes. New arms are easy to swap out and make a tremendous difference.

Drain Pump

If your dishwasher isn’t draining fully, the pump likely needs replacing. Installing a new pump is straightforward.

Door Seal & Latch

Leaks around the door indicate a bad seal or latch. Replacing both parts often fixes the leakage.

DIY or Hire a Technician?

Repairs require basic mechanical skills and some strength. If you’re comfortable following instructions and using tools,  DIY replacement of pump, motor, or internal wash parts is very reasonable. For major electrical and tub repairs, consider hiring a technician.

2. Fasten and loosen mounting screws to remove the pump *(have a bucket ready!)*

3. Position the new pump, secure screws, and reconnect wires/hoses 

4. Double check fittings sealed before restoring power
