I have Rainbird controller ESP-12-LX+ in ground sprinkler system.
Recently I am having a problem with station 5. When this station is done and station 6 starts, station 5 remains on. I manually started both stations and worked properly. Other times it would not.
I then did a “Rapid Station Test Routine”
It indicated “Open MV” then proceeded to all 12 stations and then said “CHECK”
I then switched rain sensor on. Indicator light came on due to recent rainfall.
I did another test this time with rain sensor on. Test started with:
“MV ON” then continued showing each station indicating:
“OPEN 1, Open 2 etc all 12 stations. Then showed “CHECK”
Is it possible that the controller could be bad?
NOTE: I have city water so no MV PUMP is installed
Your help is greatly appreciated

My vote is that your rain-bird valve has debris in it (#5). Ive never had a esp lx fail to where it would intermittenly run one zone then turn off. I have had them fail and always send voltage to a zone, but not intermittenly.
Rebuild your number five valve and flush it good, and give that a try.
