OFF TOPIC! Programmable timer problem

-

i wonder if 1 of solar heater experts or fish farmers etc. might help. arduino not involved part of job.

i have programmable timer on water heater. works ok hard read every display item visible i.e. time shows 88:88, in pic. there internal battery, , reads fine if turn power off. therefore assume ac power cause of problem.  hoping can fix re-arranging wiring and/or moving timer other end of sub-board shown (very small).
