Some might have read I posted, I use pressure washer on the blower.
Don't do it. It was a big mistake.

FCU casing was dripping water, one drop at a time, super irritating. There's no clogging at the discharge hose, so i wonder where the water comes from.
I pull out the discharge pan, and it was coated with scum. Use Kao color bleach to clean it up. And close up FCU.

Still it drips after a couple of days. This time I went further and try to pull out the blower, but failed to do so. However, I saw all the scum on the back of the coils. The rear coil water drips over what looks a drain, but it was fully clogged.. It's just a strip of plastic about 1cm deep. Unable to fully pull out the blower, I use finger to dig through the scum, after spraying liberally with the bleach.

I think the drip has now stopped. I still have to use that bleach to clean up more that was unreachable.

I believe by spraying water on the blower, all the dirt went upwards and stick everywhere inside, and cause this problem.

So if anyone needs to do maintenance, the best way is still to vacuum the blower. Remove those dirt before they make problem.
You can still use high pressure spray on the coils, just don't hit the blower with the water causing the dirt to rise upwards.

Painful lesson learned.

currently i am doing this exp

1st, is after normal pressure wash is done.
dissolve 10 pan treatment in super concentrated water then aim at the back drain tray water, wait 10min

then step 2, 90 degree sprayer and aim at the back tray from the top then use the same 90 degree sprayer aim facing up from below the blower (as close as i can) then again 90 degree sprayer and aim at the back tray from the top




i will try your method, to use vacuum the blower to remove the dust then spray with water

add some video to help better understand. why cant/unable as quote It's just a strip of plastic about 1cm deep. , I use finger to dig through the scum, spraying water on the blower, all the dirt went upwards and stick everywhere inside, and cause this problem.






the back drain tray is below back coil, so doing water spray might not be able to reach but can try to pressure wash by spray water upward and downward after cleaning it done, of course best is to remove blower (but i dont know how) so next time i wash i will try this

if remove blower of course can pressure wash it as it will shif the coil just enough to pressure wash the back tray

When you spray the blower with your jet, you need to hold the blower. Don’t let it spin along with the water.

why? is it to prevent the dust from spray to the fin

yes correct

 

[The_King]

yes correct

would it a better idea to vacuum the loose dust from blower then hold the blower and then spray the blower with jet/

Can if you don’t feel troublesome. I usually use a chopstick put between the blower fin then use water jet to wash the blower. Section by section.

thanks for sharing, i guess vaccum liao then use hand to stop spinning while i pressure water then once clean i try to aim the speaker at the back drain tray and blower it clean

It's a good idea to insert a stick to stop the blower from spinning while cleaning, so it doesn't hurl the black stuff upwards towards the coils.
They stick under the coil, clogged up the drain of the rear coil, which is not usually visible.

I'd recommend the use of Kao Color Bleach, in liquid form. Put it in a sprayer and spray the coils. It gets rid of the black sticky dirt and also kills bacteria, so the white slimy goo will be gone. Kao Color Bleach is oxygen-bleach, not the regular chlorine-bleach, so it's not as destructive to metal. However, use glove to handle it.

For maintenance, the A/C has two problems : black and white
Black dirt (dry)
White slimy goo (wet)

Thanks everyone who contributed to this thread! Literally took apart my ac for the first time to wash Was surprised to see so much dirt on the blower after only a few months of usage.

had everything prepared but didn’t jet spray the fins as they were still clean.

 

[The_King]

this guy use sponge to block the blower from spinning, sound like a better choice then using hand, stick etc...

 

[oldchanggold]

If every night use, even two months sufficient to see some dirt in blower…
