we are dealing with high voltage here! so please only attempt if you have some experience and a multimeter otherwise get a electrician to help out even if its just replacing the whole control panel and your not sure about that – better to get someone who knows then cook yourself to a cinder via the mains!
Surprising to see so many forums posting dead ,or sporadic behaviour in the devireg550 after 3-5 years of use. Seems to be a bad choice of components in the power board…
so to fix this, first things first is to remove the dead capacitor….
Symptoms I’ve read on theses forums correlate with my own experiences these are things like ‘display blanks out when relay eventually switches on’, or ‘no error codes displayed yet no heating’?
Also another tell tell sign is no heating even when sensor readings shows 7k-24k ohms (working sensor resistance) or heater ring wires show good values on multimeter readings yet no heating…also if the bacon/heat icon is not showing then its not heating and by measuring the load outputs it normally would show 240 v but doesn’t. Output in this case is a big fat zero reading, so to fix this, first things first is to remove the dead capacitor.(and possibly relay unit but thats an optional second step)
so you need to remove the square box like in the picture ,followed by two tiny screws on either side of the clock dial..this will release the cpu/display unit which will allow you to access the wall screws to the frame.
heres the culprit ! On removing the capacitor above it showed a reading of 0.33 uf not good ,should be 1 ,so go down to your local component store like maplins or farnell and get this exact replacement ,or like me you may have something lying around from a broken device ,(so I used an old component i found from a broken dvd player power board) although it was higher rated at 400v which is no bad thing I guess.

thats all you should need to do -within a 1min of reconnecting to the mains etc you should see the bacon symbol :) and connecting the multimeter to the load pins should now show 240 v output ,if not ,next thing would be to repeat the process and replace the relay too,but in my case the capacitor was enough for now.hot tiles and no expense(or very little) other than your time.
