Replace piezo switch.
Replace piezo switch.
Filter blocked
Remove debris from ball valve filter
Remove debris from ball valve filter

Check that water is available to the
inlet water supply.
Water supply pressure issue
Check inlet water supply pressure
and that a minimum of 300kPa and a
maximum of 500kPa is available.
Water continues to run from the flush
valve
Solenoid seat possibly fouled by debris
or scale
Solate the water supply and remove the
solenoid valve. Take out the plunger

Ensure that a minimum 25mm water
supply is connected to the flush valve.
If multiple flush valves are supplied off
the same service, refer to the hydraulic
design and subsequent pipe sizing
to allow for probable simultaneous
demand.
WC pan flush volume issue
Ensure the WELS rating of the WC pan
is comparable to the WELS rating of
the flush valve.
Incorrect timing setting of flush valve
at stated inlet pressure.
