What E5 means
Candy document E5, E6, E7, Ef and EL as a single entry with one meaning: electronic control fault, contact the technical assistance centre. Five codes, one answer, and no owner steps offered. It is worth being straight about what that does and does not tell you. It narrows the fault to the control electronics, which rules out the mechanical causes — this is not your filter, your hose or your tap. But it does not distinguish between the five, and Candy do not publish what separates them, so anyone who tells you that E6 specifically means one component and E7 another is going beyond what the manufacturer has said. This grouping comes from the older generation of Candy manuals, the CDP and CDIM era. The current generation uses a different and shorter list, which is a useful clue about your machine’s age: if yours displays one of these five, you are looking at an older appliance, and that is worth factoring into any decision about repairing it. Control boards are among the most expensive parts in a dishwasher, and on a machine of that vintage the quote will often approach what a new one costs.
What causes it
| Cause | What is actually happening | How likely |
|---|---|---|
| Control board fault | What the grouped code names. The electronics have failed or lost their configuration and the machine will not proceed. | Common |
| Connector or wiring to the board | Corrosion or a loose connector in a damp cabinet. Considerably cheaper than a board, and worth asking about before one is ordered. | Occasional |
| Power supply problem | An unstable supply or a shared socket. Candy warn separately against extension leads and against putting two appliances on one fuse circuit. | Occasional |

What it costs to fix
Typical repair cost
£90–£260
A connector or wiring repair is £80 to £140. A replacement control board is typically £160 to £260 fitted, which on an older machine is the point to weigh it against a new one.

What other owners found
Nobody has shared what worked for them on this code yet. If you have had it, you would be the first — and it genuinely helps the next person.

Common questions about Candy E5
What is the difference between E5, E6 and E7?
Candy do not say. They publish all five — E5, E6, E7, Ef and EL — under one meaning and one instruction. Anyone offering you a component-level meaning for a specific one of them is going further than the manufacturer has.
Is it worth repairing?
Get the quote before deciding. These codes come from an older generation of Candy machine, and a control board is one of the priciest parts in a dishwasher. On an appliance of that age the repair often costs a substantial fraction of a replacement with a fresh warranty.
Could it be the socket rather than the machine?
Worth eliminating, because it is free. Candy advise against extension leads and against running two appliances from one fuse circuit, noting the combined load exceeds what standard circuits safely carry. Move it to its own wall socket and see.
Should I keep resetting it?
No. Candy’s general position for a breakdown is to switch it off, turn off the water supply and not tamper with it. Two attempts at a proper power cycle is a reasonable limit; beyond that you are just repeating yourself.
