How to Replace Dishwasher Impeller: Step-by-Step Guide
Posted:February 13, 2025
The dishwasher impeller is important to your dishwasher’s efficient cleaning performance. The impeller acts as a pump and helps circulate water in the dishwasher. Consequently, it ensures that the detergent comes in contact with all surfaces of your dishes and that all the food debris goes off smoothly. The dishwasher impeller can become worn, clogged, or damaged over time and this can result in poor cleaning results. This step-by-step guide will teach you how to replace the dishwasher impeller to return your appliance to its optimal functionality. If you are encountering poor washing results or noise when the dishwasher is in operation, you can save yourself time and money by learning how to replace the dishwasher impeller.
The dishwasher pump impeller is an important part of the dishwasher that causes the water to circulate in the dishwasher during its cleaning cycles. This small but effective part operates together with the dishwasher pump to guarantee that water is evenly spread over the dishes, resulting in the best cleaning possible. The dishwasher pump impeller helps to break down food particles and also mixes the detergent with water to make the wash cycle more efficient.
The two major types of impellers in a dishwasher are the dishwasher drain impeller and the wash impeller.
Dishwasher drain impeller: This is an impeller that helps in draining the water from the dishwasher after the wash cycle. Doing so guarantees that all residual water gets expelled to avoid stagnation (odor and mold growth). The dishwasher drain impeller works to send water through the drainage system and can assist in removing any remaining debris when draining.
Wash impeller: it circulates water during the wash cycle. This ensures that water gets to all areas inside the dishwasher, especially to the spray arms, to clean thoroughly.
Below are some of the common problems with dishwasher impellers, their symptoms, and their impact on the dishwasher's performance.
Issue
Description
Clogged with debris
The impeller can clog with food particles, grease, and other debris which will make the dishwasher not perform to the expected level and the water will not drain from the dishwasher to the point of pooling in the bottom of the dishwasher.
Unusual noise (Wear/damage)
A damaged or worn-out impeller can show up as rattling, grinding, or strange noises during a wash cycle.
Impact on dishwasher performance
A faulty impeller results in insufficient water circulation, poor washing results, higher cycle frequency, and more wear on other components.
Step-by-Step Guide: How to Remove Impeller from Dishwasher Pump
When you are ready to begin a dishwasher impeller repair, you will first need to gather the tools and take necessary safety precautions before beginning the repair.
Unplug the dishwasher or turn off the circuit breaker to always disconnect the dishwasher from power.
The water supply should be shut off to prevent any leaks or spills during the replacement process.
Remove panels to access the dishwasher’s internal components. Usually, the bottom panel or toe kick panel will have to be unscrewed.
Find the dishwasher pump impeller in the unit. The pump assembly with the impeller is usually located near the bottom of the dishwasher.
Take care to remove any components that are in the way of the impeller. You may have to detach sprayer arms or other parts blocking your access.
Gently remove the faulty impeller and note its orientation. Be careful not to damage surrounding components during this process as the impeller’s position is critical to proper installation.
Install the new impeller in the pump assembly in the correct position. Make sure it is oriented in the same direction as the old impeller for proper operation.
Secure any removed parts back on your gun and prevent future problems.
Test the dishwasher to see if it is working properly after replacement. To be sure the dishwasher pump impeller is working correctly and water is circulating as it should, run a short cycle.
Essential Maintenance Tips to Prolong Impeller Lifespan
Regular maintenance of your dishwasher is important to guarantee its longevity and proper operation. Below are some preventative maintenance tips that involve the inspection of dishwasher parts to avoid future problems.
Regular inspection of dishwasher parts: Routine inspection of the key dishwasher parts, like spray arms, filters, and drain hoses should also be conducted. It’s important to check these components regularly to determine if there is any wear and tear or blockages that could cause impeller problems or prevent the washing process.
Clean the filters frequently: The filter in your dishwasher is very important to trap food particles and food debris. Clogging of these filters can be prevented by regular cleaning, which allows water to flow freely through the system without problems with impeller operation.
Check the dishwasher drain hose: Check the dishwasher parts and specifically the drain hose for kinks, blockages, or leaks. Proper drainage and minimization of future drainage problems require keeping the drain hose clear.
Clean the spray arms: Check that the spray arms can turn freely and that their holes are not blocked by mineral deposits or food particles. Cleaning the spray arms will ensure efficient water circulation, which is necessary for the best washing performance.
Keep the door seal and gaskets in good condition: Check the door seal and gaskets for any wear or damage. Water leaks can occur if the seal is compromised and the seal must be replaced to function and operate as efficiently as possible during cycles.
Dishwasher impeller replacement is essential to keep your dishwasher running at its best and most efficient. For water circulation purposes, your dishwasher needs to have a functioning impeller and regularly checking and timely replacement of your dishwasher impeller can save you from even minor issues turning into major malfunctions thereby saving you time and money.
