Replace the Internal Batteries and reprogram it.

Check that watering duration is set to a time and not "0" https://www.6ya.com/callphilipforhelp

Do you have a reset button?

These timers seem to be very robust and one has been operating for several years without any problems. After a period of rain I turned the tap off to prevent the timer turning the water on. The "err " message was there when I next went to turn the tap on. Judging by the intstructions there is an internal battery of some kind which flashes a "OP" message. I took out the main batteries and the "OP" signal started to flash, I then removed the four screws from the back of the timer but could see no obvious way of resetting it. I took a guess which luckily turned out to be correct and briefly bridged two contacts on top of the timer (see picture). The screen went blank and when I re-installed the batteries it had re-set itself to. All buttons are also working.
I imagine that there have been many of these thrown out with the garbage un-necessarily when the solution is quite a simple one. Pope would be doing a service to the planet by fitting these timers with a reset.

You have to get out your owners manual book and see what the product number is for the timer part itself inside the housing unit and replace it or if you cant then have a washing machine specialist fix it for you because the problem will only get worse and mess up your washing machine worse! I just went throgh this with my washer..

How to set up Pope auto matic sprinkler system timer. Lost my directions. Need for 6 outlets on odd days

If water drains out, then there is always a blockage somewhere on drain line.

Defrost the unit completely to get rid of ice building inside drain lines.

If that does not work , then the drain line must be unlocked using a flexible shaft.

We also had the exact same problem with our Maytag side by side. We kept getting a small puddle down on the floor under the freezer side of the unit. There was also a giant ice block puddle that had formed on the inside bottom of the freezer compartment. We solved the problem in about an hour. First, we pulled the unit out from the wall and checked behind and underneath the unit with a flashlight. The little drip pan that collects the water was completely dry. That told us that there was a plug somewhere in the drain line. We removed all of the food and shelves inside the freezer so we could access the inside, back panel. My husband unscrewed the two bolts and removed both panels. We found the problem. The drain pan had frozen and all of the water was overflowing inside the freezer compartment and ultimately out onto our floor. There was also a giant snowball around all of the wiring. We used a heat gun and gently de-iced the snowball and the ice in the drain pan. The manual also says you can use a hairdryer for this. Then, my husband used his air compressor and gently blew into the hole to clear out the blockage. We checked behind the unit again and saw that the clog had released and water was flowing into the drip pan. Problem solved. It is important to get the clog out of the drain line so that the problem doesn't occur again. We put everything back together and everything seems fine now. I am also going to check the defrost timer to make sure it is timing properly every 28 minutes or so. You need your manual for this to determine steps to check the timer. It is important for the timer to be set correctly so that the unit goes into defrost mode every 28 minutes. This will also help keep the water flowing and draining w/out having time to completely freeze up. The original root cause of our problem is we had a faulty ice-maker. It had overflowed about 3 months ago. The heavy surge of water, and the small plug in the line is what started this. Another problem we have had with this unit is the plastic tubing in the back. We had one of the lines turn yellow and crack. So every few months we pull the unit out from the wall, vacuum underneath and check the plastic tubing for leaks and breakage.

sounds like a frozen fill tube, easy to check pull out refrig and you see plstic tub running into top of freezer section from behind, sometimes theres a connector fitting half way up the tube, if not you have to cut tubing and install a coupling to repair cut(available at any harware store)after cutiin tube try blowin throughin to freezer, if you cant its frozen,un freezing somtimes challange, sometimes able to blow straight though the ice other timesi se hair dryer (from iside freezer where fills the ice maker itself. best way ive found is using my steam machine i bought from one of the infomercial.good luck!!!
