We have a guide on how to safely defrost a frozen condensate pipe here. As a result, the boiler cannot blow the products of combustion out of the flue, which prevents the boiler from lighting, or staying alight.ДЄre you currently experiencing very cold weather? If so, the condensate pipe can freeze which will cause the boiler to lockout. Why is this information relevant? Well, a frozen condensate pipe causes a blockage The condensation water then backs up in the sump. A sump collects the condensation and discharges the water. As the flue gases move through the boiler they cool down, causing condensation. This blows the products of combustion out through the flue. However, there are many reasons for the boiler to activate the F.28 code Frozen condensateДЄs part of the ignition process, the fan mixes gas and air together and injects it into the burner. In short, the boiler cannot detect a flame.

The F.28 fault code activates when the boiler fails to light once the ignition sequence has started. This fault code can appear for a number of reasons, even when there isnвЂ™t a fault with the boiler at all. This stops the ignition sparking, and the boiler increases the fan speed (and gas input) to the required level for the demand.ДЄ breakdown in this sequence can cause the boiler to lockout, displaying the F28 fault code. The gas catches and lights, and a sensor detectors the flame. This mix is injected into the burner as an igniter starts sparking. Next, the gas valve will open into the fan and the fan will mix gas with air to provide the correct mixture for combustion. Several sensors check to ensure it is safe to heat the system. When you place a demand on the boiler, either heating or hot water, the boiler starts a lighting sequence. Understand what is happening to cause F28 fault code This blog explains what is wrong and how to fix the situation. If it detects no gas, the boiler will display this code until it is manually reset. The boiler will attempt to light 3 times. It happens when the boiler cannot detect a flame inside the boiler. The F28 fault code references a boiler lockout.
