Can I clarify this please:
Press the red button for on, again for off. The button springs up after both actions.
With the cover removed...
The cleaner comes on when the switch itself is pressed once but does not stay on when the switch is released.
As the button does not hold the switch on for the cleaner to run, so the switch must be faulty. I should order a replacement. Note that I swapped the switches and still get the same problem, are both switches faulty?
Cheers
