Troubleshooting guide
Thetford toilet-care additive selection
Use this when an owner needs to choose Thetford waste-tank, flush-water, grey-water, periodic-cleaner, or daily-cleaner products without mixing unsupported chemicals.
Use this atlas to identify likely meaning and prepare for service. Shut off power, LP gas, fuel, or water when a listed appliance condition involves flame, gas smell, exhaust, generator shutdown, high temperature, moving jacks/slides, refrigerant, 120 VAC, control boards, repeated ignition failure, or a persistent lockout. Call the appliance maker, RV dealer, or a qualified RV technician for repair.
Owner-safe checklist
- Identify whether the need is waste tank, flush water, grey water, periodic deep cleaning, or daily bowl cleaning.
- Use only Thetford additive categories and product directions for the tank or surface involved.
- Record product used, tank type, odor, sensor behavior, flush-water setup, and storage or freezing exposure.
- Use Thetford support for persistent odor, sensor problems, seal symptoms, or uncertainty about product compatibility.
