PumpWise and warranty
Fault
Probable cause Recommended solution
Pump will not
start
Electrical Check power supply
Check fuse
Check circuit breaker
Inlet/outlet connections
incorrect
Check that connections are plumbed the correct way round
and all valves are open
Insufficient gravity flow Check that installation complies with Salamander instructions
Check suitability of pump – is installation in negative head
(see page 9)
Check inlet filters are not blocked
Check flow rate min of 2l/min required on both hot and cold
Float sticking in outlet Ensure no debris is in outlet area
Flow switch malfunction Contact service
Pump will not
start – ESP CPV
pumps additional
checks
Pump in wrong mode Ensure pump is commisioned in correct mode for system
(i.e. positive or negative head)
L.E.D. warning light lit See below conditions
L.E.D. 1 lit (pump hunting) Check all outlets are fully closed and there are no leaks on outlet
pipe work
If fitted to toilets ensure ball valve in cistern is not passing water
Ensure equilibrium ball valve fitted
Ensure pump is fitted to Salamander instructions
L.E.D. 2 lit (aeration –
starvation of water)
Check cold water storage is correct for installation and pump is
fitted to Salamander instructions
Flange fitted
Check pump filters are clear of debris
L.E.D. 3 lit (temperature) Is effective temp control fitted (cylinder stat or HWS/TMV valve)
Is the temperature set to 65ºC maximum
Fault Probable cause Recommended solution
Reduced/
intermittent flow
Incorrect or no
anti-aeration flange fitted
Check that installation complies with Salamander instructions
Insufficient gravity flow See above
Blocked inlet filters Ensure that all filters and shower head are free from debris
Couplers restricting flow Ensure that all AV couplers are straight and not bent or distorted
Air in system Run system on full hot with pump switched off (i.e. gravity only)
for several minutes
Check cold water storage is correct for installation and pump is
fitted to Salamander instructions
Ensure cold water refill rate is adequate for installation
Check that vents are fitted as described in instructions
Wrong size pump for
system
Ensure pump is sufficient to run the equipment
Hot temp set too high Reduce cylinder stat setting to 65ºC max or fit HWS/TMV
Pump starts with
all outlets closed
Leak in system Check for leaks
Outlet open Ensure all outlets are fully closed or capped – i.e. no dead legs
in pipework
Pump is noisy Air in system See above
Pump vibrating on surface Ensure rubber feet are fitted to pump
AV couplers causing
vibration
Ensure that all AV couplers are straight and not bent or distorted
Pump is leaking Pump exposed to mains
water pressure
Check that installation complies with Salamander instructions
Pump has suffered
chemical damage
Ensure that the pump has not come into contact with chemical
substance i.e. solder flux
Pump exposed to
excessive temperature
Is effective temp control fitted (cylinder stat or HWS/TMV valve)
Pump appears to have
leaked but not sure
Check leak is not from fitting in pipework above pump
Trouble shooting
