AC relay chatter

Hello everybody and thank you in advance for any assistance you can provide.

I have a pump control circuit that is causing relay chatter. It appears that R2 is getting enough current from the SSR timer to cause R2 to chatter. The circuit functions properly when the float F2 is in the high position, but when it's in the low position and F1 is made, that's when it chatters and actually causes the processing pump to pulsate. The reason for R2, is to control a solenoid valve to the open state, but only after the SSR timer times out.

Any help is greatly appreciated.
Circuit drawing is attached

Thanks,

Michael

The wiring diagram is sideways, and it is hard to read because of missing connections. A ladder diagram would be much easier to trouble shoot.

your drawing is certainly incorrect. If your pump/sol runs in one position, not the other (chatters), something is pulling your supply down, which your drawing misses.

Measure your voltage at your pump/sol connection during the two modes, and look for a voltage drop. Retrace your circuit or view the original schematics.
