Candy E5 fault codewhat it means and how to fix it
An electronic control fault. Candy group five codes under this one meaning and route all of them to their service centre.
Take care
Get a qualified appliance engineer to look at your Candy E5
We do not pass enquiries to a repair firm, so there is no form here. When you book a qualified appliance engineer, tell them the make, the model and the exact code or message on the display, and ask whether they carry parts for this make — that is what turns one visit into a repair rather than a quote.
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But it does not distinguish between the five, and Candy do not publish what separates them, so anyone who tells you that E6 specifically means one component and E7 another is going beyond what the manufacturer has said.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 2018 and 2019 generation of Candy and Hoover manuals — CDP, CDI, CDIM, CDPN and CDIN, and Hoover HDP and HDPN.
The manuals from 2021 onwards drop the row and replace it with "any other code": turn off and unplug the dishwasher, wait a minute, turn it on and restart a programme, and if the error occurs again contact an authorised service centre. That 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’s manuals advise against adaptors, multiple plugs and extension cables. | Occasional |

Stop — this needs an engineer
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.

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’s manuals say it is not advisable to use adaptors, multiple plugs or extension cables. Move it to its own wall socket and see.
Should I keep resetting it?
No. Candy’s current instruction for any code they do not list is one attempt — turn off and unplug, wait a minute, turn on and restart a programme — and if the error occurs again, contact an authorised service centre. Their general position for a breakdown is to switch it off, turn off the water supply and not tamper with it.
