Horstmann electronic 7. Cant get hot water regardless of what I do

[Juliet]

I have moved in 3 days to a flat which seems to have a lot of problems. I have not had hot water yet and the agent tells me I will pay for a call-out if it will be something simple and I could have found it on the internet.. So I am paranoid. The red light is on. I usually would have a shower around 1 am but there was never hot water in the bathroom or kitchen regardless of the time. I also found next to the water container that all switches were on but the isolator switch was off. Is that correct and is that a reason why it doesn't work. I read other articles but nothing works.

mission accomplished though someone is coming, Maybe one of you boys. As advised Im gonna go and get some biscuits and proper milk not that weird almond stuff ?
Never been so excited in my life

aaaand what kind of biscuits? ?

Jaffa cakes.... but that’ll just start a cake v biscuit argument.

has to be hobnobs for electricians. plumbers can make do with custard creams, red-head builders will have ginger nuts, and kitchen fitters can lick up the crumbs, along with all their MDF dust.

The switch needs to be in the timed position for it to work.
You also need to make sure that the time is set right for the clock, off peak and boost times if required.
When I test the off peak side I change the clock to 3am to force the controller to switch on the off peak element, obviously boost wont work when off peak is active.
Failing that I bet the thermal reset has tripped on the thermostats but this is best left for an electrician to check as you can be exposed to live parts.

Page 5 of this manual suggests resetting the controller if it is not functioning

Then reprogram it
