work.
Problem
Possible causes / resolution
Machine is not clean internally
after use
Lack of water or a failure to circulate within the machine. Check that
the main water solenoid valve is operating.
Make sure that the main isolating valve is open. Is the water isolator
service valve in
the ‘Open’ position?
Check that the pump is working.

after use
Check for foreign matter in the gap of the vent in the centre of the lid.
If this is blocked, remove the vent, clean it and replace it.
The jet gap must be the same around its circumference.
If the problem is with the pump you will require an exchange unit for
this part.

rectify, before making any adjustments to the latch mechanism.
