Dometic OD-5001 low heat rise or excessive flow needed to trigger

Use this when an OD-5001 needs excessive flow to trigger, has low heat rise, or behaves like cold water is bleeding into the hot line.

Owner-safe checklist

• Close unused hot and cold faucets or valves during troubleshooting.
• Do not rely only on a showerhead pause button to stop water flow.
• Close the actual shower valves after use so cold water cannot refill the hot line.
• Call a qualified technician if low heat rise or excessive trigger flow continues.
