Maytag Dishwasher Error Code F8 E4 – Simple Solutions!

1. Check The Water Supply

Start by checking the water supply valve and the water pressure.

It is important that the water supply valve for your Maytag dishwasher is turned on and that the water has good pressure to fulfill the appliance’s requirements.

Here is how to check the water supply to the Maytag dishwasher:

Step #1 Check The Water Supply Valve:

1. Locate the dishwasher water supply valve under the sink.
2. Make sure the valve is turned on and check for damage, or clogs.
3. If the valve is defective or not opened completely, replace the valve.

Step #2 Check The Water Pressure:

4. To test the water pressure, close all taps of your home.
5. Connect the pressure gauge to the kitchen sink tap. 
6. Fully open the sink tap and check the reading on the gauge.
7. If the gauge shows a reading under 40 psi, call a plumber.

Note: The ideal water pressure must lie between 40 to 60 psi!

2. Unclog the Dishwasher Filter

Although cleaning of the Maytag dishwasher should be done weekly or depending on the use, when you haven’t yet cleaned it properly, maybe there is a clogged pathway.

Any stuck debris or dirt accumulation on the filter will prevent the water from circulating inside the appliance!

The Solution?

• You just need to deeply clean the filter to free it from debris!

1. Open the front door and take out the lower rack.
2. Locate the filter from the back of the tub bottom.

6. Next, soak the filter in soapy water for about 5 minutes.
7. Then, scrub the filter using a soft brush to clear the dirt.
8. Again rinse it under running water to clear the filter of dirt.
9. Reinstall the lower and then upper filter into the dishwasher.

Note: Be extremely gentle when handling the folder to prevent damaging the piece!
