Central Locking System
1) Locks stopped working a week ago. I heard the pump running for a long time, and nothing would happen, and then the same night, the pump stopped.
2) Opened up the box and sure enough the graphite impeller wheel was shatterred into pieces.
3) Bought a replacement pump with replacement impeller wheel.
4) Installed everything back and I hear the pump running, the impeller spins 1 direction when unlocking and another direction when locking.
5) Unfortunately, the locks still dont work.
Do you think there are problems with the lines, etc or something at the door side.
Thanks. Would appreciate any feedback soon.
