Ultima Wt741 "door" Fault

[Dusty1]

Hello, i have a ultima wt741 which is 3 years old and the problem is the that the door locks but no light sppears to say so on the display. It starts sometimes but wont finish the cycle with the door fault flashing any help welcomed.

If the door lock light is flashing continuously it might be saying it thinks the door is not closed properly, possible faulty door lock or door catch not operating it properly. But if it flashes in countable cycles, such as 10 times, with a slight pause, then another 10 times continuously then this is an error code and you need to count how many times it's flashing and report that error code number.
