How to reset a dimplex storage heater?

I have had several problems with the a number of Dimplex XL6N models. All due to overheating (top front grill is never covered) and all have the same thing in common - the heating element has burnt out to the extent that themetrallic surface of the element has partially melted in places. Thermostats have been replaced but essentially nothing wrong wit them. This overheating is worrying to the extent, that when it now occurs I don't even bother repairing but buy a different model.

got CX5N and if someone wants to do anything in this particular heater about safety switch you need to take convector and storage heater controls away. Four screws, no big deal.
It's small black button on bronze round thing. Go for it. :)
Good luck.

Some models don't have a reset switch, you need to replace the thermostat as per information I got from Dimplex

I have to do this often as I manage several houses tenanted by students :
Storage heaters have a switch which may trip if anything has blocked the outlet grille (damp towel etc). Different manufacturers use different looking switches but the principle is the same. To reset it try this (Unidaire type)
First ENSURE that the power is off, by this I mean off at the consumer unit or at least the fixed fuse on the wall (you will be poking your fingers inside so be very careful).
Pull off the 2 control knobs (they are just push-fit) then remove the 2 or 3 self-tapping screws from the bottom of the cover (you will need to lay on your belly but they face forward). Then remove the 2 or 3 screws from the top face of the cover (near to where the knobs are). Do NOT remove any screws from the side of the units or you will risk the heater falling off the wall (and they are extremely heavy). After the screws are removed lift the cover slightly to clear the rear case and pull away the cover. To the top right-hand side you will see a block of connectors and controls hidden by a dull metal plate. This plate should hinge forward exposing the contacts underneath. Check again that the power is off at the wall.
Under where the "input" knob sits, in line with one of the cables you will see a small bare-metal tab with just a few millimetres visible. This is the thermal cut-out. (other manufacturers use a small metal knob ). With the back of a small screwdriver gently push down on this tab. You should hear a small "click". Push the contact cover plate back into position and before re-fitting the covers switch the power back on. Depending in whether your heaters operate during the day or not after 10 minutes or so you should be able to smell (from the dust inside) if they are working or not. Give them 30 minutes and see if they are warm. If so, switch off and replace the covers. If not try the tab again. If still no joy, try replacing the wall fuse and checking the consumer unit breaker (do other heaters work ok )? Should it still not work seek other advice, possibly from an electrician.
Hope this helps.

Hi similar problems to the above, have a dimplex xlt6n (pretty old model). It has cut out - probably due to overheating. I took the cover off to see if there was a reset button but couldnt find it. Should i be looking for something else?

Hi!
Have just found this wee blog on my search over the internet and have - 5 mins ago - taken the covers off my 2 non-working heaters - and re-set.

If this works I can safely say I have saved a callout and labour change from an electrician!!!!!

Thanks! NEJU & JIM and any others who knew how to do this.

You are both truly stars.

I'll let you know if it works.

TURN OFF THE SUPPLY
Take the heater cover off
On the top of the input thermostat switch you will see something that looks like a bare shiny metal tag
It looks like something you shouldn't touch
That's the reset button
Press/lift the tab (just in case you've not bothered to turn of the power - use a non-conducting tool)

Sorry no answer, just more questions.

Two months ago I replaced a 25 year old Dimplex XLT6N (0.85kW) in the bathroom with the model recommended by the local supplier, the Dimplex XL6N (850W).

Two problems:
- the new one gives only half the heat as the old one.I note that the instructions describe the XL6N as 6 kWh not 0.85kW

- yesterday the heater failed to come on. It is possible that the cutout switch has operated, but I cannot see how to reset it. I have taken the covers off etc. but there is nothing obviois to flip back as in the diagram in the instructions.

Any thoughts before I take it back to the supplier for a refund.

Switch off at the wall, undo the screws along the back top and lift the front cover up and forward to remove. Look for a black plastic cut out behind the thermostat, with a coin sized disc in it, press the little button in the centre, it should give a click noise. Refit cover and switch on. Heater should heat again overnight. (Depending on the model there may be screws on the front lower edge as well)

I need to replace a dial on the top of my heater (its an XLS). Do I take the front and top off and if so how. I tried unscrewing the front panel and pulled but nothing happened. Is it brute force or am I mising something here duh

What does this reset switch actually do? I looked at mine and it seems to make a contact that is touching anyway.. and given it's off when pressed..... can someone explain?

just down from the dials....all i see is a big metal plate thats covers most of the front panel.
I have remove the beige cover panel that is secured by 3 screws on the top, do i need to remove another panel by any chance to see the magic reset button?
