A) ENSURE the Bicarb inlet tubing is NOT restricted!
B) Figure right, ENSURE the Bicarb connector’s filter is
clean AND the adaptor plug opening is not plugged!
NOTE! If external leaks, “No Water”, or a Flow Error EVER occur address them FIRST!

once?

troubleshoot “V104/108 Stuck Closed”.
b) If pulling from a Bicarb jug or a Central Bicarb Delivery System (SDS) AND
[Conductivity] increases to more than 13.0 mS Valve #104 is, at least, partially
