Ian, quick question - I have the Spring analogue controller. Just lately my system has been playing up a bit. Everything works fine until I turn the water off at the pole. Occasionally the pump won't come in again when I open the valve back up for half a minute.
If the battery was flat I would expect it to shut the controller down. If the callibration was set too low I would expect the pump to cycle on full flow. If the pump was knackered I would expect it to shut down at any time.
I'm going to change the fuseholder when I get time because I can see some evidence of melted plastic although no damage to the fuse itself.
Anything else I should look for?
Hi Dave.
The damaged fuse holder could be affecting the current flow between the pump and battery as it will increase the volt drop. It is possible that the pump is struggling to draw enough current as it comes out of DE.
What type of tap are you using to stop the water flow? is it an aquadapter or tap on the hose line?
When you turn off the water flow does the system stay pressured? it sounds to me as if when the tap is turned off the Control is dead ending the pump as we would expect. It then seems the system is losing it pressure I would expect to see a delay in flow restarting if this happened as the pump has to re pressure the system.
When you turn the tap on is the pump coming out of DE straight away?
Have you recently changed the hose size, jets or using a longer pole? What is the Cal and flow set at?
