No power to immersion

[HappyHippyDad]

Morning all.

I have just been to a house where there is no power to the 13A FCU feeding the immersion.

I believe I have found the corresponding MCB in the CU although it is difficult to be sure as there is only continuity on the CPC, it is labelled water heater. There is no continuity from the CPC in the FCU to any other CPC's in the CU which also makes me think I have located the correct MCB.

It has not been working for around 6 months. The tenants say no work has been carried out and it just stopped working one day.

It does seem odd that there is a completely clean break between line's and neutral's (L-L >999Mohms, N-N >999Mohms) of the cable and the CPC is intact, barring any parallel paths (unlikely).

I have searched everywhere for a DP switch or timer switch but cannot find one. The tenants say there isn't one and the landlord is unsure.

Am I missing something obvious? The reason I ask is because I will be putting a new circuit in (easier than taking carpets/floorboards up to find fault) but it just seems like there must be another switch somewhere and that's a lot of disruption for the sake of flipping a switch!

We had a kitchen switch at my parents for immersion in a 70’s house.... now disconnected, hidden by a fridge freezer and there’s no immersion tank anymore....

is next door neighbour the same style of house? Maybe have a look in their kitchen for signs of a switch. Might be in same place??

Are you sure it’s an FCU at the tank? The 13A fuse will go regularly on a 3kW heater.

6 months without hot water?

The timer switch you mention.... is it an old e7 quartz? Or is it a proper central heating programmer?

Good idea about next door although in the present climate I may not be welcome in!

Yep, defintely a FCU. If it is a 3kW immersion it shouldn't blow.

Yes, 6 months without hot water. They said they had mentioned it to the management company many months ago and the management company said they had only heard about it 2 days ago!?

HHD: For some extra information perhaps ask the tenants what position did they find the mcb lever in when they investigated no hot water for the very first time. And ask if up until then they had had hot water and never once touched this mcb.

I've emailed the management company and suggested they get the tenants to have a thorough look through the kitchen, also to double check with the landlord and failing that I'll have another look prior to carrying out any work.

Half hope none of us find a switch as it's the first job that's come along in weeks!

Anyway, back to more important matters to see if anyone's guessed today's photo

Just realised that they are tenants... have they asked the landlord ??
