Diplomat Ceramic Hob… element or switch?

[Diplomate]

Help! I don’t have any experience mending cookers..

One of the ceramic hob elements on my Diplomat Ceramic Hob is not working. I want to be sure I order the right part.

I checked the dead Ceramic Hob Element for a continuous circuit using a
battery and bulb where the two wires enter the element. I did not disconnected any existing wires because I thought this would not make any difference to the result. The bulb lit so I am assuming the ceramic hob element is not broken.
Is this correct?

I then had a look at the Hob Energy Regulator Switch connected to the element that is Not Working. Using a mains test screwdriver I observed that when any of the other 3 working hob regulator switches are switched to ON a terminal connection opposite the Always Live Terminal becomes Live. Nothing changes with the hob energy regulator switch that is connected to the element that is Not Working, only the always live terminal remains live.
Am I right in assuming that the “11540550 – Diplomat Hob Energy Regulator Switch” needs replacing?

I don’t know my Diplomat Ceramic Hob model number but from the excellent pictures on the parts list of this website it looks the same and I’m guessing all models use the same switch?

for future readers it is dangerous to live test a machine, there is no need to,all testing should be done with a multimeter after isolating component to be tested.

unplug first one way is if the regulators and wires going to them are all the same on the hob or /and write down where which wire goes to ie s2 p1 p2 ect and colour of wire , and switch it with another on the hob and wire both back in so no losse wires. if the element works then u know 100{e5d1b7155a01ef1f3b9c9968eaba33524ee81600d00d4be2b4d93ac2e58cec2d} its the regulator or not if you unsure .
model number normally on bottom of hob some hobs have 2 types of regulators. one ending in 550 was a fairly common one, model number should be on any paper work u might still have.

Yes, thanks Smartin, I agree wholeheartedly with your safety advice. I should have tested the energy regulator switch using a multimeter after first isolating the hob.

Karv, thanks, I couldn’t find the model number of my Diplomat Ceramic Hob yesterday but you jogged my mind and I found I still had the booklet that came with the hob. So, the model number is APL 1313 (Mocca). Good job you mentioned model numbers because the switch is different to what I looked up not using the model number. The bad news is it costs about £12 more. The correct part on ukwhitegoods.co.uk is “76X3605 – Hygena, Diplomat & Schrieber Cooker Hob Control Switch” Price: £30.66. The switch I may need is for one of the two 1200w cooking zones but I think it’s the same for the 1700w zones as well. I may have to swap over the switches as you suggest to be certain it’s the switch that is faulty. I always isolate then label connections and make drawings before removing components.

Diplomat Ceramic Hob APL 1313 switch replacement continued:

I swapped over one of the existing switches to make sure the hob element is working okay and to confirm it’s the “Cooker Hob Control Switch” that’s faulty and not the element. I concluded the switch is faulty and all elements are in working order. I have now ordered a new cooker hob control switch from https://shop.ukwhitegoods.co.uk.

Diplomat Ceramic Hob APL1313… switch replacement.

I have now fitted the new cooker hob control switch I ordered and received this morning- super fast from ukwhitegoods.co.uk All the hob elements are working now, so thank you again Karv and Smartin for your help.

This is an easy job for an experienced diy kind of person to do but can take a lot of time if, like me, you haven’t tackled this before. Once I new I had to fit a new cooker hob control switch and had taken the hob apart before it took me three quarters of an hour to fit the new one but finding out how to take the hob apart and find the fault the hard, but sure, way by swapping the hob switches over took in total five hours.

If you too need to dismantle your Diplomat Ceramic Hob APL1313 to change a hob control switch make sure the hob is isolated to prevent getting electrocuted and use a multimeter for any testing. You’ll need the correct torx key to undo the case screws at the back of the hob. Lots of wires go to the switches so take your time and make a drawing of the back of the faulty switch, numbering the connections and noting the colours of the wires. Label each of the wires on the faulty hob switch, to correspond with the drawing you made as you take the connectors off, so you know for certain where to put the wires back on the new hob switch. I found I had to remove all the screws on the case to raise the switch end up on one inch blocks of wood in order to reach the nut that holds the hob switch in position. Be careful when reassembling the hob to get the back case in the right position before tightening the screws. Don’t use too much force or you could break the ceramic.
