Yep it was the Woodbridge machine, and i guess all the down time has been a mixture of lack of experience, a few minor problems with the machine, failure to identify the cause of the problems, and shear bad luck.
To be fair to them they have put everything right for me straight away, but it has really put me behind the last 2 months, but i have had a good day out of her today so hopefully it will stay that way.
it seems the main cause of all my problems were 2 things
1, the chemical i was using, Alltecs, liquid - ultimate master. Seemed to block all the machine up.
2, i filled the tank up at a customers house, at the same time as the water board were working outside, and they must have let a load of $hit get into the mains
As i ended up with a tank full of sand - dirt - grit and clay, wich again blocked up the machine and didnt do me any favours.
All this led to the pressure jumping about, the machine overheating, no water coming through the solution hose and a load of other problems.
Wich led to a new thermostat, a new pump, new solution hoses and loads of cleaning out and descalling ect.
But it seems sorted, so fingers crossed.
