7.7 Troubleshooting

Pump will not start, when the tap is opened:
• Check fuse(s).
• Check power source(s), and ensure there is
sufficient voltage to run the pump.
• Ensure pump switch is ON.
• Using a multi-meter, ensure there is power at
the pump. If not, refer to your dealer as there
maybe damaged cabling or a fault with the
fusebox.
• Is the pump hot? If so, allow to cool before
retrying.
• Has the vehicle been stored over winter? was
it correctly winterised? If no, the pump may
have frozen, causing permanent damage.
Pump runs, but will not pressurise system (i.e.
no or little water being discharged from taps)
- Not Pulsing:
• Ensure that there is water in the fresh water
tank.
• Ensure water system has been primed
correctly, (see '7.2 Priming the Water System'
on page 43), and there are no air-locks
present.
• Ensure there are no restrictions in the
plumbing.
• Ensure the inlet side of the pump is watertight
and not allowing air into the system.
• Using a multimeter check that the voltage is
between 10 and 14.5 volts. If not, refer to your
dealer.
Pump continues to run (for more than 5
seconds) after taps are closed or pump turns
on for no reason:
• Check for leaks on the high pressure side of
the pump.
• Ensure water system has been primed
correctly, as per the handbook, and there are
no air-locks present.
• Ensure the pump is securely mounted.
• Ensure the piping on the high pressure side of
the pump is in good condition (not blowing or
deforming).
Noisy or rough operation
• Check for leaks on the high pressure and low
pressure side of the pump.
• Ensure that all pipes (especially those within
150mm of the pump) are not touching any
furniture.
• Ensure the pump is securely mounted
Pump rapidly cycles (switches on or off) or
water pulses from taps, including temperature
pulsing:
• Check for leaks on the high pressure and low
pressure side of the pump.
• Ensure there are no restrictions in the
plumbing
