1D. Clean or replace affected parts. Replace hose if needed.
1E. Check voltage at toilet while toilet is running. If less
than nominal voltage of toilet (12, 24, or 32), check condi
tion of batteries and wire sizes. Check terminals and wire
connections for corrosion (heat at terminals and junctions
indicates a bad or corroded connection).
