I would blow it out with a air line .

Really not enough info to give a good answer yet... was it cooling your home good before you switched to heat? If it wasn't, then most likely your system is low on refrigerant... when it is suppose to be on, check to see that your outdoor unit is coming on, if it is on and the outside unit looks like a block of ice or starting to ice over, the defrost control board has failed and needs replaced.. hope that helps

Their a sealed system..only way is to install a piercing valve...good luck they usually always leak after that... but it won't fix the problem you need to find the leak..good luck

Power issue at breaker?, plug gfci trip?

setting is not on cooling.....

It's a "drainage system trouble" code. The compressor run light flashes in 10 flash increments. You should be able to check whether condensate is draining from the unit. If not draining, that's your problem.

Google Haier air conditioner error codes. Also check the code I see codes F0 through F4. F9 is not listed could it be a "4" instead of a "9"? F4 is the air flow sensor is off.

What is the model number of the unit?

The unit should be sloped towards the outside per the instruction manual. https://www.manualslib.com/manual/63687/Haier-Hwf05xck.html?page=11#manual If you didn't ice up the unit the water should flow freely from unit. Is the filter clean?
