Hi, hope someone can help!
We have a Watchman which has always worked perfectly. Recently, the alarm 'triangle' on the monitor in the house has been flashing, so I changed the battery in the Watchman (the round thing that goes on the tank), but the alarm symbol keeps flashing. If I turn the monitor off and back on again, the lines appear showing how much is in the tank, but after a few minutes that disappears and the alarm symbol flashes again.
Anyone know of a quick fix? Is it possible I've put the battery in upside down (but I'm sure I've tried it both ways and still have this problem) - which way up is it supposed to go?!
As we approach winter I really want the gauge to be accurate, so any ideas please? Thanks in advance!
