This dishwasher it’s my wife’s. I charge her a favourable rate!
the washing performance before it got stuck on 1 min, it was greasy. I used the dishwasher degreaser, the professional type. It doesn’t make any difference – still stuck on 1 min and no heat (although there were a lot of heat on the last wash with the degreaser until I came to use the normal wash afterwards). So I decided to take the machine apart to check the heater, it appears to be fine, gave a reading of 24 ohms so I ruled the heater out.
Checked the matrix, it was crudded up on the bend on the top left corner, flushed it out with boiling water. The tiny pocket on the very top left corner is full of crud, rather tricky to flush it out, so it’s a case of persevering. There is a similar posting as this on Dishwasher help forum, I thought this guy was mad to use drain cleaner but it seems to be the only way to get it out…I examined the pipes, it dawned on me that the dishwasher does not drain the water out directly but via the matrix. How daft is that? No wonder it gets crudded up!
It would have been easier to buy a new matrix (from labour point of view) but not available on my side for this model according to my three suppliers. – Connect/Masterpart/Qualtex.
I checked the pressure chamber, slight crud but cleaned it out. Nothing that could have disturbed the program unless it is that sensitive. The salt chamber is dirty-ish – brownish water (I have seen worse on other jobs) though I have used salt but not topped it up recently say 3 weeks. The salt light is on but there are some salt left. I live in a very soft water area. Will let you know how I got on…
PS – Why on earth this dishwasher got a double layer of skin? No wonder why it’s so heavy! Is it for quietness or insulation purposes?

No heat could mean that the module (heater relay) has a bad connection. Or that the circulating pump is not supplying sufficient water flow through the heater to operate the safety switch?

The drain system through the matrix acts as an effective water block toward external drain connections and that if the drain outlet terminus is below the water level the machine cannot syphon out!

New matrix part number 215761 (Cost around £105)

The stainless steel outer panels are a much thicker gauge and cannot easily be formed to replace the established profile. Hence the reason they sit neatly over the top!

Effin’ drain cleaner! splashed into my eye resulted in a visit to A&E then discharged 2 hours later with drops. Turned out no lasting damage (I hope) just painful swollen eye. Let that be a lesson to all engineers including myself – not to mess about with drain cleaner – just buy a new sodding matrix!
The cleaned matrix had no effect to the heater or whatsoever so it’s kind of pointless.
checked the switch on heater – working
checked the thermo on heater – closed circuit assumed working
Checked insulation resistence – more than 200m ohmstraced back to pcb – found solder came off the board – assumed the culprit to the not heating. Will check on other side of the board to see if it’s not blown, then will attempt to resolder once my eye get better.
All this trouble for my wife!
