Plumbing Troubleshooting - Swift Tourer Owner's Handbook Manual

To remove a pipe, push the collar inwards, and
then remove the pipe.
As a note, when refitting the pipe, ensure
the end of the pipe is round (not oval) and
the cut is square. If not, it could lead to
water leaks.
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 54 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 49 and 51) 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.
P LU M BI N G T ROU B LE S H OOT ING
• 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 49 and 51) 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 54 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
temperature 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 54) for information on
how to do this.
