Dometic XT water heater has low flow or cold flow
Use this when a Dometic XT tank water heater has low hot-water flow, cold flow, or not-hot-enough water from the XT mixing-valve condition described in the official manual.
Owner-safe checklist
- Stop use if hot-water temperature is unsafe or unpredictable.
- Record the XT model number, symptom, tank maintenance history, and whether the issue is low flow or cold water.
- Do not remove or service the XT mixing valve.
- Call a certified RV appliance technician for mixing-valve service or persistent XT cold-flow symptoms.
