r0452500 No Flow

[bryangauvin]

Hello all,
I have a R0452500 Jandy Sensor. My Jandy unit is displaying "No Flow" Does anyone know how to reset this? There is no daughterboard on these newer units. Its the one that has that weird box for no reason that hangs below the box.

B,

Welcome to TFP... A Great resource for all pool owners with flow problems...

I guess the first thing I'd want to know is do you actually have a flow issue? What is your filter pressure and do you have a good of water pressure coming back to your pool?

Do you have a variable speed pump, if so what RPM are you running?

Sorry, I do not know how or even if you can reset your unit... Just thought I'd throw some likely causes out there...

Let's see if others might chime in...

Thanks for posting,

Jim R.

How old is your box?

What is the box model number?

Jim,
Flow is not an issue. Pool is running fine. RPM 2250, everything is clean.

James,
The sensor is less than a 2 years old.

I saw how you "reset" the flow on the old ones with a daughterboard, do you all know any way to do it with this newer one?

model number is H0406200

Are you on A or B?

Which aquapure power box do you have?

 

[bryangauvin]

I am currently on B. Box version 02110a1005

 

[JamesW]

If the number on the cpu is 02110A10, you use program A.

Ive tried both A & B. Same results

 

[JamesW]

Put it on A, then power off for 1 minute. Then back on and watch inline box for flow light.

Ok so that seemed to work, however, this am now its back to showing No Flow.

 

[JamesW]

Does the inline box show a good flow light?

Is the system powered when the pump is off?

Ok, so I sucked it up and bought a new flow sensor. Seems to be working fine for the FLOW issue now.

However, not its bouncing all over the map for Salt readings. One minute it shows 0, the next 4200, the next 1900 and says low salt. Any idea how to fix this?
