Fault Notes
• Blocked Filter
There is NOT a fault code for a blocked filter. The large surface area of the filter makes a
blocked filter very unlikely. If the filter was completely blocked, and the pressure switch had
not moved to the FULL position after a maximum fill of 5.5 litres of water, the machine will
drain and continue with the cycle. The symptoms of a blocked filter would be Poor Wash
Results and a very quick cycle.
• Filling
After the initial drain period, it is normal at the start of a cycle for the machine to pause for a
period before filling.
• Heating Element
An open circuit heating element can display either the heating time out fault code
(Fault Code 6) or the open circuit heater fault code (Fault Code 10), depending on the cycle
in progress or the phase of the cycle when the heater fails.
If a dishwasher has an open circuit heating element, the machine may run for up to 75 minutes
before a fault code will display.
• Programme Times
The times in the handbook and displayed at the start of the cycle, are average times and will
be affected by the following points:
• Inlet water temperature below 19°C
• Tab option enabled
• Water hardness setting set to positions 4 or 5
• Condition of the heating element (limescale built up)
• Excessive foam caused by using tablets with a small or light load.
NOTE: - The display is not a count down timer. It is normal occasionally for the same time to
show for an extended period.
• Machine Starts up for a few minutes when not in use
The machine inlet valve is 'letting by' and water is leaking into the machine when not in use.
Providing the machine is plugged in and the door closed (it does not have to be switched on),
once the water in the machine is enough to operate the pressure switch to full level, the
machine drain pump will energise until the pressure switch resets to empty (plus 30seconds).
Note: - Fault code A:2 displays if the water letting by is fast enough to be recognised by the
water turbine.
It is recommended before a module is replaced or when the fault is not obvious, the
heating element is tested for continuity and resistance to earth at its terminals, with the
heater disconnected.
