Is your dishwasher bottom rack hard to slide in and out? This common issue is often caused by worn or damaged plastic rollers on the underside of the rack. Over time, these wheels and axles can deteriorate, making it difficult for the rack to move smoothly. The good news? Replacing the dishrack roller assemblies is an easy, budget-friendly repair that can restore your dishwasher’s functionality in no time.
With basic tools and about an hour of your time, you can tackle this straightforward DIY project. In this guide, we’ll show you step-by-step instructions on how to replace the rollers on a dishwasher rack, using a GE dishwasher as an example.
How to Replace Dishwasher Roller Wheels
Follow these steps to diagnose the issue, replace the damaged rollers, and restore your dishwasher’s functionality.
Diagnose the Problem
- Pull out the bottom rack completely until resistance is felt, then gently slide it in and out to check for catching, resistance, or uneven movement.
- Inspect the rear roller assemblies on the underside of the rack for cracks, chips, excessive wear, or misshapen parts.
- Spin the wheels to check for stiff rotation or grinding.
- Clear any debris blocking the rack path.
- Check that the rack is not bent and sits flat and centered without twisting.
- Confirm that the issue is due to damaged rollers before proceeding with repairs.
Obtain the Correct Roller Kit
- Identify the dishwasher model number and order the correct replacement roller kit from a reliable source.
Shut Off the Power and Water Supply
- Turn off the breaker supplying power to the dishwasher to eliminate the risk of shock.
- Shut off the hot water supply line under the sink.
- Disconnect the intake hose from the hot water valve, using towels to catch any residual water.
Remove the Lower Rack
- Fully extend the lower rack, lift it upward to release the rear wheels, and remove it completely.
- Place the rack on a towel or tray to catch any water drips.
Detach the Old Rear Rollers
- Examine the attachment of the rear roller assemblies to the rack and locate the clips securing the axles.
- Press down on the clip while twisting the roller wheel to detach it from the axle.
- Remove and discard both rear rollers.
Install the New Rollers
- Align the new axle and wheel assembly vertically with the slotted bracket on the rack.
- Apply firm pressure while rocking slightly to insert the axle until it clicks into place.
- Repeat for the other roller and rotate both wheels to check for free movement.
Reinstall the Rack
- Slide the dish rack back into the dishwasher, aligning the rear wheels with the tub’s support channels.
- Slowly lower the rack, allowing the wheels to drop into the channels without bending the axles.
- Center the rack left-to-right within the tub and push it fully in to confirm smooth gliding.
Restore Water and Power
- Reconnect the intake hose to the hot water valve and turn the water supply back on.
- Inspect for leaks as water pressure resumes.
- Restore electricity by switching the circuit breaker back on.
Confirm Proper Operation
- Start a wash cycle without dishes to verify the smooth motion of the repaired rack.
- Run a test load to confirm proper cleaning performance and rack stability.
Tips for Maintaining Your Dishwasher
Replacing worn parts like rollers is just one way to keep your dishwasher in great shape. Regular maintenance can help prolong its lifespan and keep it running optimally. Here are some tips to consider:
- Inspect and Clean Regularly: Every few months, check the door gasket for cracks or wear and clean the tub interior to prevent grime buildup.
- Clear the Filter Basket: Remove and rinse the filter basket to eliminate trapped debris that could hinder cleaning efficiency.
