Candy E8 fault codewhat it means and how to fix it
The water heating element is not working correctly, or the filter plate is clogged. Candy bundle two very different problems into one code.
Take care
Does the code return after a thorough filter clean?
The right answer depends on what you can see. Pick the one that matches.
Choose the option on the left that matches what your appliance is doing, and the answer for that case appears here.
No, it has gone
The element is fine and there is nothing to repair.
Clean the filter monthly from now on. This code was the machine telling you it had been left too long.
Yes, it comes straight back
You have eliminated the free half of the code, which narrows it usefully.
Book an engineer and tell them the filter is already clean and the code persists.
What E8 means
Candy give E8 — which appears as Ei on some models — as the water heating element not working correctly or the filter plate being clogged. That is an unusual pairing to find in one code, and it is genuinely useful to know about, because the two ends of it have wildly different costs. One is a free clean and the other is a component replacement. The logic behind the pairing makes sense once you see it. The element heats water that is being circulated past it. If the filter plate is clogged badly enough that flow through the system collapses, the water sitting against the element does not behave the way the machine expects, and it cannot distinguish that from an element that has stopped heating. So Candy report both possibilities together and leave you to eliminate the cheap one first. That is what makes this worth attempting yourself. Clean the filter plate properly — not a rinse, a proper scrub with the mesh out and a brush — and run a hot cycle. If E8 goes away, the element was never the problem. If it comes straight back on a clean filter, you have narrowed it to the element and you can say so when you book, which should stop anyone charging you to discover it.
What causes it
| Cause | What is actually happening | How likely |
|---|---|---|
| Filter plate clogged | Named in Candy’s own wording alongside the element. The free half of the code and the one to eliminate first. | Common |
| Heating element failed | The other half. In hard water areas scale insulates the element until it eventually cooks itself, which makes this close to a wear item. | Common |
| Scale on the element | The cause behind the cause. Worth addressing with softener salt regardless of what this repair turns out to be. | Occasional |
| Temperature sensor or wiring | The machine misreading a working element. Less common, and established by measurement rather than assumption. | Occasional |
What to try yourself
Switch off at the wall and take the filter assembly out. Separate the coarse cup from the fine mesh — they come apart, and people often clean only the outer part.
Scrub both under a hot tap with a washing-up brush until the mesh is genuinely clear when you hold it to the light. A rinse is not enough here; this step is the whole point of trying.
While the filter is out, check the spray arm jets are clear and that both arms spin freely by hand. Poor circulation contributes to the same complaint.
Refit everything, top up the softener salt if it is low, and run the hottest programme with the machine empty.
If E8 returns on a genuinely clean filter, it is the element. Book it, and say you have already eliminated the filter so nobody charges you to find that out.

What it costs to fix
Typical repair cost
£0–£220
Time on site
40 minutes
Free if it is the filter, which is a realistic outcome and the reason to try. A replacement heating element is typically £120 to £220 fitted, and on many machines it is integrated with the pump housing which pushes the cost up.

Common questions about Candy E8
Why does one code cover two completely different things?
Because the machine cannot tell them apart. The element heats water that is being circulated past it, so if the filter is clogged enough to collapse the flow, the reading looks the same as an element that has stopped working. Candy report both rather than guessing.
My machine shows Ei rather than E8.
Same code. Candy document E8 and Ei together with one meaning, and which you see depends on the model and display.
Will the machine still wash without heating?
It may still run a cycle, but it will not clean properly and it will not sanitise anything. Dishwashers rely on hot water to shift grease, so a cold cycle leaves a film on everything.
Would salt have prevented it?
It helps. Keeping the softener topped up slows scale forming on the element, and scale is what kills elements in hard water areas. Use dishwasher salt only — Candy warn that other salts contain insoluble particles that degrade the softener over time.
