Hi all , Iv bought a new pump and controller and it keeps pulsing when in use.
Iv calibrated the controller, but when the water comes out the brush it’s starts of really slow then speeds up to normal then after a few minutes it slows to a dribble for a second then back to normal and repeat!

Any ideas please?

Cheers in advance 👍

Have you tried to bypass the controller and connect power straight to pump

Iv changed to normal connectors so il see how I get on today , cheers everyone 👍

Good luck.

I was gonna say battery but sounds ok from your readings.

I've had a battery in the past and it was dud even with all the charging I could give it.

Now I just use Halfords car batteries 😁

Done leisure batteries not impressed

So after changing the connectors , the 1st job was fine and then played up a bit on the 2nd job and then it was fine after that. Only thing that’s doing my head in a bit is the leaky connectors now. Maybe I need to wrap some ptfe tap around the hoselock threads

I have had this more than a few times , once it was a done in battery , once it was a slight kink in the hose way back on the reel , i unwound it all off let it pressure up and it sorted itself out , once it was blocked strainers and once it was due to using hoselocs with the built in waterstops , i knocked them out and all was good .
Just a few things to look at before you buy a battery or rip the wiring out !

How do you knock the water stops out?

Hi Shrek the pulsing is because the calibration is slighty to low for the flow rate and the pump is dropping in out of DE. Good news is the answer. Either manually increase the calibration by a value of 10 Or when you auto cal in step one set the flow rate to the one you want to use ( EG 50 ) We only use the value 30 to give an indication of step one it does not have to be 30.
