I would try blow-drying it with warm air using a hairdryer, or to warm it up using the steam from a boiled kettle to see if that works.

Good luck!

Surely if you do that it will expand the filter head making it even tighter? We had ours changed for the normal Truma inlet and did away with the filter. Saved a fortune on filters!

That's what I thought.
Surely it's the opposite and should be packed with ice if possible.

Not many caravans are fitted with filters nowadays. We just use a filter jug . You don’t need it filtered for washing up or shower.

I only go by my previous experience when jar lids or stacked metal/plastic/glass containers were stuck many a times - gentle heating helped to release them.

I'm inclined to agree. If the blue cap screws onto the inlet it need heating to release it. If it screws INTO the inlet it needs cooling.

'Standard' Truma water inlet, common to many vans.
Potentially two locking forces keeping it from undoing easily, first, the rubber sealing ring is binding, second the thread is binding, both potentially from over tightening.

Heating with a hair-dryer (NOT anything as high powered as a hot air paint stripper!!!!!) may cause the cap to expand enough to free off, worth a try. Heating 'stuck' items is a well proven engineers trick, but the 'heat' has to be relevant to the materials involved!

More brutal! Place something like a piece of wood or rigid plastic (preferable NOT a metal object like a screwdriver unless prepared to replace a broken cap!) against one of the four protrusions on the rim, and tap gently but persistently with a mallet or light hammer to rotate in a ANTICLOCKWISE direction. Once it's moved a little, it should be possible to undo by hand.

Safer, but requires purchasing a tool, use a 'Boa Constricter' band wrench (https://www.diy.com/departments/boa-11022-21enb-baby-boa-strap-wrench-soft-grip-10........ - also available from many other outlets). Brilliant tool, I use one on my water butt where the caps are near impossible to remove if tightened enough to prevent leaks!

The filters in these units are pretty much unnecessary if taking water supply from a fresh water tap on a mains water supplied site. Service engineer took mine out on first service, explaining it was more of a health risk unless changed near monthly, as grew algae, than not having a filter at all. The cap fits and seals happily without a filter in place.

Bring back the engineer who serviced it: it’s not fit for purpose or has been incorrectly fitted with a cross thread.

That's what I would do first to be honest, as he/she caused the issue to start with!
