The water in the internal drain could be reversing inside the drain instead of being drained away. The clogging could be the main suspect. You can fix this problem by simply clearing the clogged drain.

If there is notable cracking or clogging, the tap water usually used for cooling will seep from the plumbing system and enter the furnace. For repair, the humidifier should be removed for urgent repair or replacement. Use a manual to carry out the replacement.
