Candy [E2] fault codewhat it means and how to fix it

Candy give E2 as the dishwasher not filling with water, with four checks: make sure the water supply is open, make sure the supply hose is not bent or crushed, make sure the drain pipe is at the proper height, and — with the water closed — unscrew the hose from the back of the dishwasher and check that the "sand" filter is not clogged. The drain-hose check looks odd on a fill code, but it is theirs: a hose hooked into standing water can siphon the machine as it fills. Their installation section adds the figure the checks rely on, a supply pressure between 0.08 and 1 MPa, and the advice to run new or long-unused pipes for a few minutes before connecting so that sand and rust do not clog the inflow filter.

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: on machines fitted with WATERBLOCK, the water supply hose should not be cut, because it contains live parts. There is a sensor and a valve built into the hose assembly, with mains wiring running through the sheath to operate it. It is an 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, or too short, it gets replaced with the longer one Candy supply.

1. 1

   Check the tap under the sink is fully open, turning it right off and right on rather than judging by the handle.

2. 2

   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. On WATERBLOCK models the manual states it contains live parts, with mains wiring inside the sheath; if the electrical box on the hose is damaged, Candy say to pull the plug immediately.
3. 3

   With the tap closed, unscrew the inlet hose at the back of the dishwasher over a bowl and check Candy’s "sand" filter in the connection is not clogged; rinse it until it runs clear. If the tap-end connector has a gauze too, do the same there.

4. 4

   Check where the drain hose ends. Candy include its height among the E2 checks: it should discharge into a standpipe at least 40 cm off the floor and no higher than 85 cm, and must not sit in standing water where it can siphon the machine as it fills.

5. 5

   Reconnect, straighten the hose so nothing is crushing it behind the machine, and run a short programme. If the code stays with the tap open and the filter clean, the supply pressure — Candy want 0.08 to 1 MPa — is a plumber’s question and the inlet valve an engineer’s.
