Symptoms

  • Cycle will not run
  • Continuous draining
  • F8E4 or E4 shown

Common Causes

1
Loose water-supply connection

An unseated fill-hose washer leaks into the base.

2
Disconnected float switch

The base float switch is unplugged or stuck.

3
Excess suds

Using regular dish soap creates suds that trip the sensor.

How to Fix It

  1. Unplug the dishwasher and check the fill-hose connection and washer for leaks.
  2. Tilt the unit back briefly to drain the base and reset the float.
  3. Use only dishwasher detergent — never dish soap.
