My sandpiper pump lost its prime again. The pump was constantly pumping and would work fine in the bay. I am not sure what the problem is but the chemical seemed foamy and white like the picture to the left. After I removed the outlet hose the chemical took longer to prime this time.
There was a hydraulics problem today. The best we could tell the pressure gauge blew and fluid shot out of it all over the wall and the ceiling. I noticed it because the conveyer stopped working. Then the conveyer started working again without doing anything. William replaced the pressure gauge.
Greg fixed my bay problem today.
1) First we narrowed it down to which function had the problem. It was just presoak.
2) Next we disconnected the presoak solenoid for that bay. This is to rule out a bad solenoid coil. Still had the problem.
3) Next disconnect the presoak wire in the equipment room. Not sure if we disconnected the right wire but still had the problem.
4) Next disconnect the presoak wire from the terminal block. This stopped the problem. Greg said that the wires were corroded. Which is bad. This fixed the problem.
5) The next step would have been to disconnect from the switch.
I tried a new relay and like Greg said it made no difference. One coil wire is going to the timer load the other to the 24 vac coil in. The throw wires go to the equipment room.
One throw wire goes to the 24 volt power supply (white lower) and the other wire is not used? It makes no sense. I must have checked wrong. I was getting frustrated and tied to look at another bay then broke it. Had to figure out what the problem was then quit. I think maybe I need to just rerun all new wire to the bay and read about hooking up the timer.
I forgot to mention that the relay switch goes back and forth making the noise. I believe this means that there is a wire short? Who knows? It also just does this when the throw wires are attached.
