Water heater’s condensate trap repeatedly overflows or drips from joints.

Safety: Turn off power; condensate is mildly acidic.

• Clean trap: Remove the Weishaupt condensate trap, clean thoroughly, and check for cracks.
• Prime trap: Fill the trap with clean water before reinstalling to ensure proper siphon action.
• Check drain: Ensure the building drain is not blocked and that the condensate pipe has continuous fall.
• Seal joints: Reseat and tighten all trap and hose connections to prevent drips.
