Daily to Annual Maintenance Checklist

Regular maintenance is essential to ensure the optimal performance and longevity of your Bosch water heater. By following a seasonal maintenance checklist, you can help prevent issues and ensure that your water heater operates efficiently throughout the year. Here's a comprehensive checklist to guide you through the seasonal maintenance of your Bosch water heater:

• Ensure that no water leaks are evident around the outside of the water heater, the pressure relief valve, or from the installer-supplied plumbing connections.
• Inspect the air intake and exhaust terminations on the exterior of the home, and ensure they are unobstructed by snow, ice, shrubs, or any other material.
• Visually inspect the exterior of the water heater and the vent piping for signs of discoloration or physical damage.
• If any water leaks, discoloration, or physical damage are found during visual inspection, please shut off the power, gas, and water supplies to the water heater and contact your installer or a qualified service person immediately. Do not attempt to remove the front cover yourself!

• Inspect and clean the inlet water filter.
• Inspect the heat exchanger for soot, water leaks, or compromised seals.
• Descale the heat exchanger (especially in areas with high mineral content in the water).

• Inspect exhaust venting and air intake piping for blockages or damage.
• Inspect the heat exchanger for soot, water leaks, or compromised seals.
• Inspect the burner for damage or blockages.
• Inspect the pressure relief valve for leaks and test for correct operation.
• Inspect and clean the inlet water filter.
• Inspect the condensate trap for leaks, blockages, or damage.
• Check and clean the spark/flame sensor electrodes.
• Inspect and clean the air filter that is mounted on the front of the fan.

By following this seasonal maintenance checklist, you can help prolong the life of your Bosch water heater and ensure that it continues to provide reliable hot water for your home. Regular maintenance can also help you identify and address potential issues early, saving you time and money in the long run.
