They are sensitive to large extention cords. My father in laws pops reset when a small cord is used. If internally shorted- motor will continually pop the reset even plugged direct to outlet. Check voltage at outlet.

well depends did u use it in cold tempatures if so no it was u. if not then most likely or could have been just a crazzy thought here that there was a electrical discharge when it was pluged in and cracked the block on it but honestly thats 1/10000000000000 chance of happening. or it overheated and cracked it but relistically if its new then just take it back and play dumb or if its still under warrenty play dumb and get it fixed. aslo u can search for a new part on craigslist or ebay. last but not least if its not uner warrenty or new to take back or u cant find a part either thru the ones i listed or by calling the man. ur last resort is to just throw it away.

Yes, the water should be turned on first but if it only ran for a minute or two it should be OK. Most late model pressure washers have an automatic shutoff when the trigger on the wand is released. Turn on the water and then the machine and then squeeze the trigger on the handle of the wand and the motor should start as soon as the air is cleared from the line by the flowing water (about 10 seconds). If the unit was put away wet last season you may need to clean the nozzle with a piece of wire too.
