Creda EcoResponse storage heater

[Custom45]

Hi
Not sure if this is best place to ask. I have a Creda EcoResponse ER500 storage heater. Fitted about 7 years ago. This year however it's been acting up. It has about 10 heat level settings. On around settings 1-7 it seems to have stopped working, i.e. in the mornings I find it is cold to touch, no heat generated overnight. Settings 8-10 it works, although maybe not as well as it should.

Thermostat on its way out? Something else gone wrong?

I'm not having much luck getting through to anyone at Creda and this heater seems to have been discontinued a while back, can't seem to find spares.

Any help greatly appreciated!
Thanks,

Does seem to point to the thermostat if part of it works. Can it be dismantled and looked at and reassembled? Or does it look like an enclosed unit?

There are usually manuals available on line, I think Creda have a site for searching for them

Could be this https://www.uk-spares.com/products/...er500n/er500n-series-a-c/dimplex-dh09004.html or this https://www.uk-spares.com/products/...mplex-87389b-old-partcodes-87389-dh09005.html Only one available & unless you can establish which is faulty it would probably be cheaper & better in the long run to get a new radiator.

Will Dimplex parts work on Creda?

Just seen this on Creda website .."Our sister company Dimplex", never knew that, since 1987 according to Wiki

Thanks for the replies, I'm away from home for the next few days, but will have a look at the heater when im back. Pretty sure it can be opened up, yes. When I installed it the panel came off for the thermal bricks & heating elements bro go in.

The control panel works ok, it just doesn't seem to heat on low-medium settings.

Is there a way of testing the thermostat? When I get it open I'll post some pictures. Thanks.

Unfortunately the diagram. does not tell you what the inputs & outputs that should be available so it would be difficult to tell anything other than the voltage that was supplied to the elements.

Opened the heater up. Would the thermostat be housed in this unit?

Could it be the switch it's wired into? I have a multimeter, what would I be testing, other than power coming to the switch?

Top left of the heater, looks like one of the connectors has browned a bit, burn marks?

Connector is very brittle and started to break apart when I touched it. The wiring appears to be intact though.
