1 valve works, two don't

For some time the system worked perfect. Now I  have two sections that don't work. It turns out that the signal to activate the valve is too short. When I  put a meter on it and then activate the valve the meter jumps to 28v for about one second then drops to zero before the valve can move. Conversely the one that works stays at 28v for much longer. I have rebooted and reset the system.  Any ideas?

Dear customer,


There may be a problem with the current to your water valve. Could you please check if the wiring is loose and measure the resistance of the water valve to determine if there is a short circuit or an open circuit?


Thanks,
