Are you finding your machine is struggling for pressure?

In many cases, you may find the problem lies in the cleanliness of the solution tank filter. Before calling technicians or paying a servicing fee, check and clean the filter.

Portable vacuum suction problems?

Is the dump valve closed? These can sometimes appear closed when they’re slightly open. Try fully opening then re-closing the dump valve before continuing further. If this doesn’t work, another cause can be related to the vacuum intake filter located in the waste tank. Check and clean before using your machine.

Machine won’t switch on

This could be caused by a number of things. Before calling a technician, check the power source and the extension lead by plugging in another appliance to make sure there is no fault. Check that the fuse has not been tripped, which would stop the power to your machine.

Water pressure problems?

Loss of solution pressure and water flow is another challenge some face from time to time. Make sure the garden tap is turned on before continuing further, please be aware some outside garden taps are on a timer, this may also affect your truckmount water pressure.

Vacuum problems?

Is the dump valve closed? These can sometimes appear closed when they’re slightly open. Try fully opening then re-closing the dump valve before continuing further. The that isn’t the case, another possible cause could be the waste tank lid. Test the lid by making sure it is properly fitted and closed.

Heat Problems

One potential cause is the heat bypass valve. A lack of heat is caused by the unit bypassing too much water through the bypass vale – it may be faulty and need to be replaced.

TH40 Turbo won’t spin

A potential cause is the solution filter. Make sure to check and clean before continuing. It is located just after the male quick connect on the handle.
