Can I lay down my dishwasher to repair it?

[treefitty]

Hi guys I need to get to the underside of my integrated dishwasher to fix a fault.

There were no issues with it draining itself so the sump should be pretty much empty but there is water in the salt dispenser etc.

Am I likely to cause any damage by lying I down or do I need to drain it first?
Do engineers do this or try and work on it still upright?

Thanks as always

Put a towel on floor ,depending where pres switch is lay on left will be ok if it's on the right.

Thanks. The pressure switch is on the right but the pressure chamber is on the left.

Is it the switch or the chamber I need to avoid damaging and tilting it on to?

Switch. Lay on the left will be ok.
