Why Does YourMaytag DishwasherShow F8 E4 Code?

Water ends up in the wrong place when there is an internal leak or malfunction inside your dishwasher. This triggers the F8E4Maytag dishwasher. So, let’s delve deep into the causes triggering this issue:

1. Clogged Drain Filter

The drain filter in aMaytag dishwasheracts as a guardian for thedrain pump. It prevents fooddebris, sediment, and other small objects from reaching the pump.

Over time, these objects can accumulate in the filter, obstructing the smooth flow of water and hindering proper drainage. This trapped water can overflow into the dishwasher’s drip pan, and then trigger the F8 E4 code.

2. A Leaking Inlet Hose

This inlet valve is like an artery delivering fresh water to yourMaytag dishwasher. It connects to thewater supply valveand transports water through theconnector housing. Over time, this hose can develop leaks due to several reasons, such as:

  • Wear and tear:With age and constant exposure to water pressure and temperature fluctuations, this hose weakens and becomes cracked and damaged.
  • Loose connections:Improper installation or a loose connection at theback of the connectorcan create a weak point where water can escape. Ensure thetightness of the couplingis secure to prevent leaks.
  • Physical damage:Accidentalkinksorblockagesin the hose can restrict water flow, leading to increased pressure and potential bursts or leaks. Regularly inspect the hose for any visible damage.

A leaky inlet hose can allow water to escape and collect in the dishwasher’s drip pan. This may eventually trigger the F8 E4error code.

3. Faulty Drain Pump

Thedrain pumpin yourMaytag dishwasherremoves wastewater after each wash cycle. For this purpose, it relies on a powerful motor to pump water out of the dishwasher and into the drain line.

A malfunctioningdrain pumpmay struggle to remove water effectively, causing it to back up and pool in the drip pan, triggering the F8 E4 code. You can diagnose a faultydrain pumpIf thedishwasher motorseems to be straining. Also, if thepump keepsrunning even after the cycle is complete, it indicates a problematic pump.

A malfunctioning pump causes water to back up and generates the F8E4. Apart from casual wear and tear. the pump’s impeller can have accumulatedclogsordebrisobstructing its operation. Furthermore, faulty wiring or a malfunctioning control board can disrupt the power supply to thedrain pump.

4. Overloaded Dishwasher

Overloading the dishwasher with dishes or using excessivedishwashing detergentcan cause water to spill over and accumulate in the drip pan. Sometimes, using the incorrect type of detergent (like non-automatic types) can createexcessive suds, which may eventually overflow.

5. Incorrect Installation
