What is actually happening
A flashing light is a fault code being reported in the only way the machine can. On most makes the pattern of flashes or the code shown identifies the fault precisely, and the two most common are a drain fault and the anti-flood float. Note the code before switching anything off — it is the quickest route to the right diagnosis.
The Leisure fault codes that point at this
A Leisure dishwasher will usually tell you what it thinks is wrong before anyone opens it up. These are the codes we hold for this make that relate to lights flashing:
- H03 — The dishwasher can't confirm that the valve which switches water between the spray arms has moved to the position it was asked for, so it stops the cycle.
- H04 — The dishwasher has lost a sensible reading from its water temperature sensor, so it won't carry on heating.
- H06 — The dishwasher hasn't taken in enough water in the time it expects, so it has stopped the programme.
- H07 — The dishwasher isn't getting the water hot the way it expects, so it has stopped the programme and flagged a heater fault.
If yours is showing one of those, that is a much shorter conversation than a general fault — tell us the code when you book and the engineer can often carry the part.
The usual causes on a Leisure dishwasher
- A drain fault with water left in the base of the machine
