Sir this complaint how Daikin U0-04 error occurred

[@BonMj]

Welcome bro

[@jinshen55]

dear sir, I had this error code U0 also but the technician who came suggested a system reprocess. Is this a standard way of addressing and investigating the cause of low refrigerant volume?

[@BonMj]

How is the pressure.
Standing pressure?
Running pressure?

[@jinshen55]

@@BonMj Thank you for your quick response. I really do not know as I am the client. I was not comfortable with the technician's approach so I asked. Without checking, technician was quick to suggest it, a costly one at that to help him diagnose. When is a system reprocess done actually?

[@jinshen55]

@@BonMj Yes I just remembered it was 80psi and he charged it with additional refrigerant up to 120psi

[@BonMj]

@@jinshen55 may insufficient gas

[@jinshen55]

@@BonMj thank you for your help. You are generous. Even after adding refrigerant, the aircon stopped working after about an hour with blinking green lights. A reset makes it work again but stops again after an hour or so. Error code is still U0 so am wondering because refrigerant has already been added

[@mdsadamahmed1208]

Good information Sir

[@BonMj]

Thanks

[@MrRandyj72]

I didn't see a nitro tank. Were you purging the system with Nitro when brazing to prevent corrosion inside the braze?

[@Darny1able]

mate your old school its shocking people dont purge OFN when brazing

[@MrRandyj72]

@@Darny1able I worked 6 years for Daikin and now with Mitsubishi. They both still require purge. Do shit right or do it your way.

[@muruganantham595]

I need a suggestion from you about this U0 error sir , last time I'm checking the gas at the time of compressor start up suddenly goes down below 30 psi , I found that was body coil valve faulty .
Now I'm changed the total set of motorized body coil valve and outdoor thermistor also . Now the cooling coming below 12°c but the system suddenly cut off after taking 7 or 8 A in outdoor
This is Daikin RZR50LVVM.

[@BonMj]

Suggest u check the high pressure sensor

[@muruganantham595]

High pressure sensor also have a continuity

Mr Bon, my daikin error code is U0 and after top up R410 4 days later not cold and now i think leaked, should i do a pressure test using nitrogen or maybe just change the EEV and then top up?

[@BonMj]

If you confirm is leak,must do pressure test

老师，前几天我检查一个外机3mks 71也是U0 内机 3个fcu都闪灯! Gas pressure is Ok .3 个 valve Ohm reading 也是Ok . 难道是Valve body 坏了？很奇怪为甚3个同时坏？reset 一下可以走机!大概2到3天后又blinking 😂

Boss
System 1 to 1 daikin inverter
u0 error code
all 55 ohm is normal operation?
Gas is 0 thankyou

[@BonMj]

Red colour wire to other wire.
The reading normally is around 47ohm.
55ohm should be ok.
Suspect insufficient gas or valve body unable to open.
