Thermo king s 600 HELP no alarm code.

Hey, i tried to pull the drain hose off the wall of the reefer but couldn’t take that off ‘cuz the unit is so hot.i feel that everything will be fine if the water comes out from the drain but its not coming. I need to find out tomorrow. i will try to take that off after delivery tomorrow morning and will let you know.
I can’t belive that the unit is working on the high rpm since Friday and my head is fckd up because of the noise…
Btw when it reaches at the temperature set point(-10),the rpm returns to low and the temperature slowly drops back to 0 and high rpm starts again and It takes a long time to drop back to -10 and never shift to defrost mode unless push the button manually and no water comes out.

 

It was on Continuous mode since friday. Just delivered the load and got some pics of the water tray. And saw only the passenger side of the tray got frozen.

 

So I should check the drain tubes from the wall of the unit outside, right?

 

View attachment 566341 I put the air inside of the drain hose and a lot of dirt came out to outside. Should i put the air on the other side too? I mean to the connector? Or will i get damage if i put the air in it??
