On a job this evening, done the usual prespray etc. Went to rinse and my unreliable Powrflite pfx 1350 dead, dead as a doornail. Turned on pump 1 ok turned on pump 2 ok and then when I turned on the pump it cut out, nada. I had a backup machine thank god but guess what the flipping pump didn't work, I could pee harder. Any ideas why the machine cut out. This is not the first time it's happened, is there a fuse inside the machine that might have gone or something. Had the machine full of water cos there was no water on the job, could water have caused it to trip because I have to lie it down in order to get it into the van. Very very annoying.
