Dometic OD-5001 showerhead pause causes cold-water purge

Use this when using a showerhead pause button or navy-shower pattern causes cold water to purge through the line before hot water returns.

Owner-safe checklist

• Run the shower continuously during troubleshooting so flow through the heater stays steady.
• Avoid cycling only the showerhead pause button when checking the heater.
• Close the actual hot and cold shower valves when finished.
• Call service if cold-water purges continue during steady normal flow.
