Fp230B Replenisher Pump Not Working


Recommended Posts

I've got a replenisher pump (n4) not working on a fp230b. I get 100v across the wires when operating and i've checked the connections. Do i need a replacement, and what might it cost? Or is there any other trick in the book? The issue came after having the machine off for a while.

If you had the lab turned off for a certain long time - the pump may be clogged by a dried chemistry.

Remove the pump and check for rotation of a wheel.

Also you can check workability of a pump in menu section: input/output check 

if the pump works well check SSR (solid state reley) located on the power PCB. looks like a chocolate bars...

they are responsible for turning oN and OFF of the pumps.
