I have a challenge xtreme 1800 pressure washer model DW1840bv ,which I have only used twice, went to use it today and it keeps cutting out as if power is intermitant . when first plugged in splutters on and off, then permanantly off! Checked plug and switch but no obvious fault. Please can you suggest another cause.

Water feed seems o.k. , but I think I have just remedied it, disconnected the lance and turned on, the water came out fine without turning off or being intermitant! Think the lance is the problem.
Thanks for your suggestion though.

Check water feed, leave switched off when you plug in
