Lamona [No water supply]what to check

The display shows E:02 — on the LAM8676 and LAM8376 with the tap symbol lit beside it — and Howdens word the condition as no water supply. Their entry is two short checks, water valve on and fill hose not kinked, and in the LAM8676 and LAM8376 manuals a third line: press the start button twice to reset. That reset is worth noting because it is the only one Howdens publish anywhere in the Lamona dishwasher documentation, and the LAM8304 and LAM8607 editions leave it out.

E:01 has none, which is a quiet piece of design logic — a machine that failed to fill has usually just been interrupted and needs telling to try again, whereas the drain and leak conditions want dealing with rather than dismissing. Take the reset in the right order, though. Pressing start twice on a machine whose tap is still closed simply repeats the failure. Fix the cause, then reset. The two causes Howdens name cover most cases and both are free. Taps get closed by whoever was last working under the sink and never reopened. And fill hoses get folded against the wall when an integrated machine is pushed back into its housing, which on a fitted kitchen happens more often than you would think — every time the floor is done, every time something behind it is investigated.

There is a third cause they do not mention that is worth a look while you are there: the small gauze filter where the hose screws onto the tap silts up with grit from the mains over the years, and almost nobody has ever cleaned it. The manual does give a figure for the supply itself — an operating pressure between 0.03 and 1.0 MPa — and its problem-solving table lists insufficient water fill against "Check mains water pressure. Fill hose kinked."

1. 1

   Check the water valve feeding the machine is fully on. Turn it right off and right back on rather than judging by the handle position.

2. 2

   Pull the machine out far enough to see the fill hose along its length and straighten anything folded or crushed.

3. 3

   While you are there, close the valve, put a bowl underneath and unscrew the hose from the tap to clean the gauze filter in the connector.

   The manual’s rule before any maintenance is to switch off the appliance and disconnect the mains plug from the socket. Expect water still in the hose however carefully you close the valve.
4. 4

   Reconnect and turn the water back on, then reset: on the LAM8676 and LAM8376, press the start button twice as the manual instructs. On other models, hold the Start / Pause / Cancel button — the panel labels it "Cancel 3 sec." — for three seconds and start a programme again. Do this after fixing the cause, not before.

5. 5

   Run a short programme and watch the connection at the tap for weeping.
