Symptoms Of A Bad Circulation Pump
Not Draining At All
If your dishwasher stops working during the drain cycle, this is the first and most obvious sign that the drain pump is broken.
This is a big problem because the appliance can’t get rid of the greywater and keep washing your dishes. Also, if the dishwasher continues to use dirty water, the dishes will become increasingly dirtier.
Therefore, you must inspect your drain pump to determine if it is the cause of your dishwasher’s inability to drain.
It Is Draining Too Slowly
The whole point of a drain pump is to help move water quickly out of the dishwasher so that gravity doesn’t have to do all the work.
So, if your drain pump is in good working order, it should only take a few minutes to drain all of the water from your appliance.
If you notice that your dishwasher is taking too long to drain, that means the drain pump isn’t working as well as it should. You don’t have to wait for the pump to break down before getting it checked out.
Water Standing After Wash Program Is Over
At the end of your chosen wash program, there shouldn’t be any water left in the dishwasher. This is for the final phase of a wash cycle to drain any excess water by forcing it down the drain hose.
A dishwasher with a broken drain pump, on the other hand, will leave water in the machine even when it shouldn’t.
So, if you look in your dishwasher and see a puddle, you should check the drain pump and its electrical connections.
If there are no clogs and the drain pump is hooked up correctly, you’ll probably need to buy a new one.
Low Buzzing Sound
In addition to how well the appliance drains the water, you can also listen to weird sounds.
For example, if your dishwasher keeps making a low humming sound, this is another sign that something is wrong. The drain pump is making noise because something is stuck in it.
A very loud squealing noise coming from inside the dishwasher is another thing to listen for. This problem is more likely to happen with older dishwashers that have been used for a long time because it means the bearings are worn out.
Your dishwasher drain pump, like many other parts of appliances, needs bearings so that the impeller can turn smoothly, even at high speeds. So, if the bearings on your drain pump aren’t in good shape, it won’t work right.
When the bearings are broken or worn out, it is hard for the impeller to turn. But what’s more important is that it will also make the noise you’re hearing.
Leaking Water On The Floor
Last but not least, a bad drain pump can also cause water to leak out of the dishwasher and onto the floor. That’s because water builds up in the dishwasher, but the pump doesn’t push it out through the drain hose.
as more water gets into the dishwasher, some of it will flow out of holes that lead to your kitchen floor.
How To Test A Bad Dishwasher Circulation Pump
- Perform an empty wash cycle to determine whether the drain pump is making an unusual noise. If you do not know where the dishwasher’s drain pump is, listen closely to the bottom of the appliance.
- Turn off the washing machine and open the door. You must gain access to the drain pump of your washing machine.
- Clean the interior and outside of the pump motor. If you have a clogged pump or a drainage problem, this can assist improve the situation. It can also assist you in determining whether there are any issues.
- If your pump motor is unclean, wipe it down with a disinfectant wipe. This can aid in obtaining accurate readings from your meter. If your engine passes inspection, it can also improve its performance.
- Examine the motor of the drain pump. This is not testing in the traditional sense, but it will help you diagnose the problem. If there are shattered bits or something wrong with the food, you already know it has gone bad.
- Clean out the pipes of the drain pump. This will prevent you from incorrectly identifying issues and also increase the performance of your washer. If your drain pump is functioning properly, cleaning out the piping will be the quickest approach to ensure that water flows freely.
- Utilize your volt millimeter to measure the resistance. A good drain pump motor will only provide resistance between 30 and 40 ohms. If it has more or less, it is undesirable.
If the test proves your circulation pump is bad, replace it as soon as possible.
