Cheers Ched that’ll help him it is Saturday and if it’s anyone I’m thinking of in the sales of window cleaning equipment then you’ll have to sort it yourself,I really urgently needed a part sent out to me Thursday for Friday so I can work this Monday,I double then treble checked I was getting the right 2 parts that are essential for me to be able to solve the problem only to receive 1 correct part and the other urgent part that went with it.
Terrible awful service I was assured that this was checked by hand and eye only to find out when I got them that 1 barb was so small it dropped through the female and out the other side,good job I know a plumber and can do a little DIY myself or this would have cost me 100s and 100s of £ in lost income.
I have spares of absolutely everything apart from this small essential part I thought I had in my toolbox 🧰,never buy 1 of anything have at least 1-2 spares including poles-hosereel motors-chains etc you’ll lose far more than they cost you if you can’t work.
If the company is that bad at customer service with a 3 week old reel I would speak to my credit card company and request a chargeback!
OK so back to the problem.
If it's reeling on it's own then it is probably as Spruce has said a failed switch and is shorting the contacts closed. The quick easy fix, if the OP is any good at diy, is to find a replacement high current switch. Halfords only list a 25Amp switch so not really high enough current but you could give one a go as a temp measure. Amazon have this
https://amzn.to/3rLHZtc which is a 50Amp momentary switch at about £12 (momentary = only makes connection when pressed and disconnects when released).
All the switch is normally doing is taking 12v in and then when pressed it allows electricity to flow to the reel motor. At a real push you could just touch the 2 wires together but that might be tricky when trying to reel in and control the hose.
If the OP has a bit more skills then it's probably best to replace the supplied 'high current' switch with a relay and a light duty switch as using a switch for high currents isn't the best way to do it although it is a very simple system.
Hope that helps better.
