My one shot suddenly stopped working the other day. It took about ten button presses, it came on, I turned it of by pressing the button and that was it, it never worked again. Is that the battery or something else? There was moisture in the controller. Im going to buy a Univalve tomorrow in the mean time. Shame because the one shot was very good for a long time. Any ideas?

Moisture and electronics don't go together. This could be the cause of your problem.
Try removing the battery and putting the unit in a container of rice for 24 hours to draw the moisture out, then replace the battery with a fresh one and see if this helps.

I dropped my phone in the tank last week. I put it in a bowl of rice for three days. When I turned it back on I found I'd lost every contact number ...... except    Uncle Bens'

What controller are you on about that had moisture in it?
Spring pump controllers and one shot units are  sealed to IP64 stopping water ingress apparently.
If it's the fob have you tried a new one/spare?

Some people haven't got a clue :  HAVE YOU TRIED A NEW  BATTERY

I was trying to establish what had moisture in it first as was clear as mud.

The remote defaults to 'on' at power up. Effectively pressing the fob disconnects the relay by making it go the opposite way. This is a line of sight device.

If your One Shot is not working check:

1. If the DIP switches in the receiver have been changed? Check fob channel and check positions of DIP switches. Also, ensure the channel on the fob and receiver are the same.

2. The fob battery is flat. Replace or check with a meter. The fob battery should be 3.0V (battery size CR2032).

3. The receiver has been damaged (possibly due to a miss-wire or water ingress). Observe correct polarity when connecting to the 12V battery. These are DC devices.

4. The receiver has locked up. Please disconnect from the battery for 30 seconds then reconnect. Red to +ve (positive) and black to -ve (negative). Press and hold fob button. Does pump respond?.

5. Check with pump disconnected but red and black connected to power. Operate fob. Can you hear Standalone's relay clicking? If 'no' check the wiring and in particular the connectors. A loose connection may mean the receiver is not powered or not able to switch the pump.

Note: If the relay clicks but will not operate the pump, then check the brown cables and connectors as these switch the pump.

6. Check the wiring to the manual. Is it connected properly?

7. Has the fuse blown? Has the in line fuse blown (as per the manual) in the connection to the pump? If 'yes' then replace it with 7.5A fuse.

8. Is the operator behind a building? Or is sight line obstructed? Raising the transmitter can help extend the range.

9. Mounting the receiving antenna as high as possible will increase range.

10. Avoid multiple presses of the fob as this will cycle the pump on and off.

Most likely is the battery. The Fob has a small red LED on the fob if this lights when the button is pressed then the fob is transmitting. If not then change the battery. On occasion if teh fob is pressed repeatedly the relay is switching on/off rapidly this can lock the receiver. Remove the fuse to power the unit down completely. Leave it out for 2 mins then replace. This will reset the receiver.  If it has had water in then the unit may have shorted.
