Title: Backpack cicuit board
Post by: Moderator David@stives on November 21, 2006, 07:21:08 pm: Has anyone had to replace the printed circuit board on a sureflo backpack and if so how much ?

I have borrowed one off a friend and i have broken it, the switch was not working properly and now it goes straight to number 4 setting and will not turn off via the switch.

Make sure switch is making contact.

Yes speak to Andy at Williamson pumps, the circuit boards can definately be replaced! The switch is apparently the common problem because it is the only part on the cicuit bopard not encased in the protective resin.

I have subsequently bought another Shurflo after my initial problems with first backpack and am currently monitoring my new one. My plan is to put some silicon around the switch next week to keep out the damp. Will let u all know how i fare!

I can remember your post

http://www.cleanitup.co.uk/smf/index.php?topic=27044.0#msg206785

I have had a closer look , if i tap the switch gently i can go through the speeds if i touch it normal it comes on setting 4 then wont switch off unless i disconnect the battery or stop the flow of water.

Regarding the circuit board have you tried heat shrink rubber,

Dave

I know it sounds daft. But water and electrics is a bad marriage.
So I keep the pack as dry as I can.

Thanks Ben, It has served me well for over a year now.

Post by: Mr. S on November 21, 2006, 11:16:21 pm: Dave i'd definately say switch on circuit board, i know this is a big problem with shurflo backpack as i had a very lengthy discussion with williamson pumps, order a new cicuit board mate.

With regard to heat shrink rubber, where would i get some from? I still intend on trying the silicon sealant first.

I now bring my new backpack indoors every night to snuggle up in the warm!! Im going to order a new circuit board for my old one shortly so ive got a spare!

Gazzasp8, cos i do wfp upstairs and trad down i tuck the lever into my belt where my hip bucket is
