pool pump wont shut off

I have a 2 HP hayward pump that wont shut off even in service mode.  I have to manually shut the breaker to the power.  Any suggestions why this is happening?

Hello Printer - The most common cause of the pool pump not shutting off at the control panel is a faulty relay. What is the make and model of the control system?

the system is about 12 years olf.  its a jandy system with a control panel in the house as well as the mail control panel outside.

If i put the mode in service mode, the pump still stays on and have to shut the breaker.

If it were colder I would say that the freeze protection might have kicked in but we are not quite there yet weather wise. It sounds like you have a relay issue. The pump relay for the Jandy control system is part number R0658100.

Hopefully this helps. Thank you for shopping with INYOpools.com!

where would I find the exact part inside that panel.  If i remember the relay doesnt look as big as the item number you sent me

I actually just went out to the control board and hit it a couple times and it works now.  I guess something is loose inside

It could be something loose but more than likely its the relay. Tapping a bad relay will do the same thing. If you open up the control panel and remove the panel that covers up the cables, you should see the relays.
