Why You Might Need to Keep Resetting Your Viessmann Boiler and What to Do

If you find yourself constantly resetting your boiler, it’s a sign that there’s a deeper problem that needs fixing.

Simply resetting it over and over can actually harm your Viessmann boiler in the long run.

Here’s what might be happening:

  • Your boiler could have a technical issue, like a faulty pump, a water leak, an electrical problem, or a frozen condensate blockage.
  • If you’ve tried to fix it and your boiler still isn’t working right, there’s likely a bigger issue that needs a professional’s look.

If this is happening a lot, it might mean your boiler is old and keeps breaking down. Instead of spending more money on fixing an old boiler, it could be smarter to buy a new one. A new boiler can save you money on repairs and energy bills over time.

In short, if your boiler keeps needing resets, get a Gas Safe engineer to check it out. And if your boiler is old and unreliable, think about getting a new one.

Step-by-step guide to resetting a Viessmann boiler after fault code

Step 1: Locate the Reset Button

First, you need to find the reset button on your Viessmann boiler. This is typically located on the boiler’s front panel. Look for a button marked ‘Reset,’ often highlighted in a different colour or labelled with a circular arrow symbol.

The exact location and appearance of the reset button may vary depending on your boiler model, so refer to your boiler’s manual if you’re unsure.

Step 2: Turn Off the Boiler

Before attempting to reset your boiler, ensure it’s safe to do so. Turn off the boiler using the main power switch.

This is an essential safety step to prevent electrical issues while resetting the system. Wait for a few minutes to allow the system to power down fully.

Step 3: Press the Reset Button

With the boiler powered off, press and hold the reset button. The duration you need to hold the button can vary, but typically, holding it for about 5 seconds is sufficient.

If your boiler model requires a different approach, such as the new Vitodens 050 or Vitodens 100, your user manual will provide the specific instructions.

Step 4: Turn the Boiler Back On

After you’ve held the reset button for the necessary amount of time, turn the boiler back on using the main power switch. This action will initiate the boiler’s restart process.

It may take a few minutes for the boiler to reboot and start operating normally again fully.

Step 5: Check the Boiler’s Display

Once your Viessmann boiler has restarted, check the display panel for any error codes or messages.

If the reset was successful, the boiler should return to its normal operation mode, and any previous error codes should be cleared. If you see new error messages or the same issues persist, it might indicate a more significant problem that requires professional attention.

Step 6: Monitor the Boiler’s Performance

In the days following the reset, keep an eye on your boiler’s performance. Ensure that it’s providing consistent heating and hot water.

If you encounter further issues or the boiler does not maintain its performance, it’s advisable to contact a certified Viessmann technician for a thorough inspection and any necessary repairs.
