UK Rutland's dk6680 air filter

[Tickle]

Hi all I have this air filter, it works when inturn it on

It has 3 settings for power, when I click it or use the remote to turn to power 2 or 3....it turns off.

Originally this was fine I could slap the top and it would turn back on but I'm now making a spray booth for my air brushing and need it to turn on to the other higher settings. I can't slap it outside of its case haha

No signs of damage to the circuit board burns or anything. Is weird.

Any help or advice would be great please

If it were me,
I would change all 4 relays.
they are the blue square objects.
you will need some decent soldering skills to do it without damaging the circuit board.

At least it's only a single sided PCB - that's a rare thing these days.
