Dometic RV toilet fault codes
RV toilets (electric/macerating and cassette) use indicator lights for tank-full and power status rather than numeric codes.
How to read the code
Read the indicator-light colour. A red/full light usually locks out flushing until the holding or cassette tank is emptied.
