Going crazy trying to figure out this error. The tub is acting very crazy. Will start pumps and air and sometimes i could start one pump only with an error "188" when i try and start pump 2 (everything stops when 188 is displayed). Sometimes I can get 2 pumps going with finally the air causing the error. Fooled around with the wiring as i thought t was the transformer and somehow it worked fine for two weeks or so ... but now it started acting up again. Any help ... please!
