Neff 80cm Induction hob

[RocketMan]

T48FD23X0/03 FD 9807

Tenant complains hob cuts out occationally and also occasionally causes the CU to trip.
She assures me it’s happened when using both sides of the hob but then she says she’s not 100{e5d1b7155a01ef1f3b9c9968eaba33524ee81600d00d4be2b4d93ac2e58cec2d} and she has some memory issues…bless her but not useful when trying to diagnose.

Nothing obviousl. No issues with the mains connection point. Nothing obvious on any boards.

Powers boards are pretty dam pricy as well but but power modules are almost reasonable in price.
Operating module – not sure without being 100{e5d1b7155a01ef1f3b9c9968eaba33524ee81600d00d4be2b4d93ac2e58cec2d} sure both sides are at fault whether this is the issue.
Given the tripping of the CU I’m more inclined to think it’s something with hefty power a power module.

I have asked the lady to keep a record of which ring she’s using so I’ll check in with her in a few days.

Any useful suggestions or advice would be helpful.

Thanks in advance…

Did you check the ventilation as it could be overheating, just a thought.

most of the time if a power module blows it wont work again. most electronics destroys itself when things go pop

its seems to only do it when drawing power. could even be the wall switch or bad connections in that

Look in the instruction manual see if the basic settings are where they need to be also induction hob can trip the electric as anything that is connected to mains has a leakage to earth which can cause tripping i always advise type A circuit breaker

Another thought for you – check what the power rating is for the circuit (is the hob max power more than the breaker?) – you can limit the maximum draw of these hobs in the user settings (Page 18 of the user manual).

Thanks. I fogot to mention. No oven below. Large deep 30cm drawer beneath and a gap between the work top and the drawer for ventiallation.

Thanks. I did activate the switch a few times to see if it “felt” alright which it did. Obviously the long big load test is best.

Thanks. It has it’s own cct. Ovens are seperate and it’s been fine since install. Current tenants have been there a couple of year and no issue until recently.

Hi, An update on this one.

On my first visit I checked the isolator switch for the hob. It felt okay and no sparking. It turned on and off with no issues.

To cut a long story short…it was the cooker isolator socket in the end. It was replaced as perhaps this is the issue. No signs of burning or issues with the switch.

The customer has had no issues at all in nearly 2.5 weeks since the switch was changed.
