Used it for first time today and was ok first 2 houses but then when I switched it off it wouldn't turn off using the flow control with or the on off switch the power is always there and when I plug pole hose in it starts straight away, Gardiners advised me to switch it on and off several times in case switch was was stuck but that didn't work and I need to get back in touch with them to get it sent back so they can look at it, anyone else had this problem or any idea what it could be?
Cheers
