Mastertech Washing Machine Manual — |verified|

The problem wasn’t that the washing machine was broken. It was that it knew something I didn’t.

E1 or E10: Usually an Inlet Water Error. Check if the tap is open or if the filter is clogged.
E2 or E20: Drainage Error. Your machine can’t empty the water. Check the drain hose for kinks or check the coin trap filter at the bottom.
E3 or E30: Door Lock Error. The machine thinks the door is open. Make sure it clicks shut firmly.
E4: Overload Error. The machine has detected too much weight. Remove some wet clothes and try again.

This is often caused by using too much detergent. Reduce the dosage according to the manufacturer's packaging. mastertech washing machine manual
