I'm sorry to hear of your DHP-H problem.Please tell me the type and the rating of the device that's tripping.
Is it an MCB or an RCBO?
OK. What is the rating of your appliance?
OK. I wasn't implying anything with my question, but I still need to know the manufacturer's specification for the rating of your appliance. I believe there are different versions of the DHP-H, so I can't make any assumptions.
On paper that should be no challenge to a 32A MCB, but they don't last forever, so something worthy of consideration is a failing MCB.If you know what you're doing with electrics, you could test out this possibility by swapping MCBs with another domestic circuit, like a 32A socket circuit (usually a ring final).
New MCBs can be faulty, but if you're convinced that it's not that then I would verify that the appliance is drawing as little as you think, e.g. with a clamp meter.
