If your Honeywell Gas Detectors display a 'Pump failed' message, it could be due to several reasons. First, check if the inlet probe is blocked and remove any obstructions, then press the [Y/+] key to reset the pump alarm. Another potential cause is a contaminated water trap filter which should be replaced. If the pump is bad, replace the pump. Be careful not to allow water condensation inside the unit.
