PLUMBING TROUBLESHOOTING
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' LED is illuminated.
• 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.
• The pressure switch may need adjusting.
See page 62 on how to do this.
Pump runs, but will not pressurise system
(i.e. no or little water being discharged
from taps) - Not Pulsing:
• Ensure water in source is present (onboard
tank or aqua roll).
• Check in-line pump filter is free from debris
and correctly fitted.
• Ensure water system has been primed
correctly, (see pages 57 and 59) and there
are no air-locks present.
• Ensure there are no restrictions
in the plumbing.
• 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.
• Ensure the inlet side of the pump (including
Truma inlet and in-line filter)
are watertight and not allowing air into
the system.
• Ensure the pump has good voltage.
• Check (using a mulitmeter) that the voltage
at the pump is between 10v-14.5v.
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, (see pages 57 and 59) 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).
• The pressure switch may need adjusting.
See page 62 for information on how to do
this.
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 tem-
perature pulsing:
• Check for leaks on the high pressure and low
pressure side of the pump.
• Ensure there are no restrictions in the
plumbing
• The pressure switch may need adjusting.
See Section (page 62) for information on
how to do this.
