Our 16 year old John Lewis own brand dishwasher (which has clearly done us well!) Has stopped heating the water. I suspect the element. I managed to pull these 2 components out (the mug is for size reference!). The one on the end looks like a motor and the one in the middle looks like some sort of pump. They both have some sort of impeller/propeller thing going on. But could the one in the middle be the element? On the Internet some elements look like the traditional kettle type but some look similar to the this. Any advice? A new dishwasher is on the cards but thought I'd see if i could fix it first.

I expect they are both pumps. One for draining, big one for circulation. A heater would have a couple of big spade connectors going to it,be mounted to a metal panel or into a casting with a rubber sealing ring around it, poking into a sump and have probably a cylindrical thermal shutoff switch bolted nearby.. Could be the thermal shutoff switch as much as the heater. I dont know how old our dishwasher is.. it started leaking after maybe 5 years but a replacement pump manifold with a better design was bought as a spare...didn't rely on silicone that split with vibration. I think its nearer 20 years old now.
John Lewis are basically rebadged Zanussi so good quality. The picture shows a circulation and an emptying pump neither of which have heating elements so looks like yours has either an element within the wash cabinet , looks like a kettle element or an inline heater after the circulation pump which is longer and slimmer and heats the water as it passes through to the cabinet. Further digging may reveal an inline heater and a simple continuity test will tell you if it's toast ... Sent from my SM-G960F using Tapatalk
Or possibly...if they're like a Bosch, the main pump and heating element are combined (thing on the right in your pic?) into a "heat pump". The element looks more like a circuit board (PTC heater?) than a kettle element. Ours blows up about every 18 months due to limescale causing hot spots. You have to buy the complete unit. I'm a dab hand at replacing them. Like this... https://www.ebay.co.uk/itm/153822472948
The one on the far left looks ikea to me, probably a flurgen from the Flurhen Durgen range designed by Birk Sigge Pekka. No heating element in them. I looks for part numbers on gubbins from white goods to ID what it is.
Worth checking that all the small pipes going to the sensors aren't blocked. There's mot many, as it could be a sequence thing, not heating till it knows it has water.
I will delve deeper this evening and see what other components I can see. Thank you for your input folks. Much appreciated. P.
Our 7 year old Howdens / indesit had the heater element fail. It is an in line unit, looks like a 4in tube with a couple of spade connectors on it. very easy to replace once you know the sequence of removal. Continuity test in situ was a bit tricky due to access, but it confirmed the fault once it was out.
Those look like a drain pump and the circulation pump, Which means you should have a reasonable element elsewhere, not one of the modern bosch type ones which are fragile, Check on Espares for correct part,
Got this Bosch on gumtree up the road for £50. Thought I'd take a punt. Plumbed it in and off it went. Works better than the old one did! (For now!). Sorry @art b if it looks like I'm ignoring your advice. That said this one is well retro! Thanks for for your help folks as always. P. Sent from my SM-G780G using Tapatalk
