brettline bl-70 "188" error
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!
Brettline BL-70 Board Capacitor Could be the Culprit
New member here. I feel compelled to respond to this even though it is a year later. I had all the same symptoms, plus, with several devices activated (e.g 2 pumps, or when the heater tried to kick on) the topside would freeze with LEDS flickering. Ordered a new topside (6 weeks!) which turns out was not the problem. Same issues. Checked transformer voltage; all good (you can find a troubleshooting manual on several websites). I also could not find out how to check the actual connector pins for the ones that supply power to the ribbon cable/topside, so no luck there. Another forum mentioned undersized capacitors being a problem on this board. So I had a closer look, and lo and behold, a brown burn mark and leaked electrolyte from a black tube-like 470 microfarad 35 volt capacitor (bottom right corner of board, near the P1-P2 transformer 12V board power spade connectors). This might explain your crackling sound. I unsoldered the capacitor from the board, put in a 50 cent new one (470mf, 50volt which was all the store had, but higher voltage rating is Ok, I believe), and presto, it works. By the way, somewhere I saw someone mention the number 24 being the first thing displayed upon power up. That is normal; I think it means the filtration cycle is set on a 24 hour schedule (instead of 12). Hope this helps someone out there. This cost me 2 months and a few hundred bucks (unnecessarily), thankfully I didn't spring for a new board (another 200 hundred). Parts in Canada are $$$$. My gut says this was a good digital pack in its day, and worth keeping alive if for a moderate cost.
