Candy E2 fault codewhat it means and how to fix it
The dishwasher does not fill with water. Some models show CHECK WATER or NO WATER in words instead of a code.
Take care
What E2 means
Candy give E2 as the dishwasher not filling with water. On models with a text display rather than a numeric one, the same condition appears as CHECK WATER or NO WATER accompanied by a short audio signal, which is a good deal more helpful than a number and worth knowing if your machine words things rather than coding them. Most of what causes this sits outside the appliance and costs nothing to check. But there is one thing on a Candy that must not be treated as ordinary plumbing, and it is stated plainly in their manual: the water supply hose should not be cut, because it contains live parts. On machines fitted with WATERBLOCK there is a sensor and a valve built into the hose assembly, with mains wiring running through the sheath to operate it. It is a electrical component in the shape of a hose. Shortening one to fit a new kitchen, or repairing a split with tape, is not a plumbing bodge — it is working on a live cable. If the hose is damaged, it gets replaced.
What causes it
| Cause | What is actually happening | How likely |
|---|---|---|
| Tap closed or partly closed | Free to check, and the first suspect if anyone has been working under the sink. | Common |
| Inlet filter blocked | The gauze screen in the connector at the tap end, silted with grit. Common wherever the mains carries sediment. | Common |
| Hose kinked behind the machine | Created when the machine is pushed back into its housing. Easy to spot once it is pulled out again. | Common |
| AQUASTOP or WATERBLOCK triggered | A Candy safety device that has operated and is now blocking the supply deliberately. With AQUASTOP a red mark shows in the window on the hose. | Occasional |
| Inlet valve failed | The valve is no longer opening to admit water. The genuine repair, once the supply itself is proven. | Occasional |
What to try yourself
Check the tap under the sink is fully open, turning it right off and right on rather than judging by the handle.
Look along the hose for a small window with a red or coloured indicator in it. If a red mark is showing, a safety device has operated and the hose needs replacing rather than investigating.
Do not cut, shorten or tape a Candy inlet hose. The manual states it contains live parts, and on WATERBLOCK models there is mains wiring inside the sheath.With the tap closed, unscrew the hose at the tap end into a bowl and rinse the gauze filter in the connector until it runs clear.
Run the tap into a bucket briefly to confirm you have a strong flow. A weak one means the supply is the problem, not the machine.
Reconnect, straighten the hose so nothing is crushing it behind the machine, and run a short programme.

Common questions about Candy E2
My display says CHECK WATER rather than E2. Same thing?
Yes. Candy use the text form on models without a numeric display, sometimes as NO WATER, with a short audio signal alongside it. The checks are identical.
Why can I not just replace the hose with a normal one?
Because on many Candy machines it is not a normal hose. WATERBLOCK models have a sensor and a valve in the assembly with mains wiring running to them inside the sheath, which is why the manual says the hose must not be cut. Fit the correct part for the model.
There is a red mark in the little window on the hose. What is that?
AQUASTOP has triggered. It monitors the hose itself, and once the red mark appears Candy’s position is that the tube must be replaced. It is a consumable safety device that has done its job, not a fault to reset.
