Last Update date : Sep 21. 2020
4E Error

The 4E (4C) error indicates that the washing machine has detected that there is a problem with the water supply.


Most common reason for this error are:

• Water supply valve is blocked by foreign material or kinked water supply hose.

• The water supply valve terminal is not connected

• The warm water and rinse connectors are wrongly connected to each other

• PCB terminal from the drain hose to the detergent drawer is not connected


Follow the below troubleshooting guides to resolve it:

• Make sure the drain hose is inserted properly and is not kinked.

• Make sure the hot and cold water valves are completely open, and the hoses are not kinked.

• Check to see if the water hose mesh filter is not blocked. See the steps below showing you how to do this. You should clean the water hose mesh filter at least twice a year to prevent build up.

How to clean the water hose mesh filter

Follow the below steps  to see how to clean a blocked water hose mesh filter.

1 Turn off the water source to the washing machine.

5 Screw the hose back onto the washing machine.
6 Turn on the tap and then make sure the connections are watertight.
