Troubleshooting
Fault
Probable cause
Recommended solution
Pump will not start
Electrical
Check power supply (appliance plugged in and electrical power on)
Check fuse
Check circuit breaker
Inlet/Outlet
connections
Check that the connections are plumbed in the correct way round and all
valves are open
Insufficient mains flow
Check that the installation complies with the Salamander instructions
Check inlet filters are not blocked
Check stopcock and all isolating valves are fully open
Check natural flow rate minimum of 3litres/min
Over temperature
Leave unit turned off for ten minutes to cool down
Then re-attempt start up routine
Natural flow >10lpm
Normal pump function due to sufficient flow.
Reduced/
intermittent flow
Insufficient flow
See above
Blocked inlet filter
Ensure that inlet filter is free from debris
Air in system
Run system on full cold for a whole house install, or full hot in a combi
boiler install, with pump switched off (i.e. mains water supply only) for
several minutes
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 against
other pipework
Move pump away from contact with other pipe work
Pump running hard
Check filters and unblock if necessary
Pump is leaking
Pump has suffered
chemical damage
Ensure that pump has not come into contact with chemical substance i.e.
solder flux
Pump exposed to
extreme temperature
Ensure adequate frost protection
Pump appears to have
leaked but not sure
Check leak is not from fitting in pipe work above pump
Check condensation build up – drain holes in the base of the pump casing
should allow excessive water to drain off
