My simer model 3986 ocaisionally does not start, is there anything that needs to be cleanded or lubricated with the switch mechanism?

Check the float for proper operation, chances are it’s stuck in a position that’s calling for the system to be on (as if there’s water in the basket) or its failed.

Yes, I think it's this one -

Sounds like a faulty switch on the float. Try to hold the switch up by hand and see if it stays running, if so you may need to lube the switch. If not then it sounds like a manufacturer defect and needs to be returned.

Thank you for posting your question here on Fixya.com.

The orientation for a sump pump/check valve are the pump is in the bottom of the pit, the discharge pipe leads up into a check valve, usually very close to if not threaded into the pump discharge, and then the pipe continues up and out to wherever your water discharges to. The weep hole needs to be below the check valve.

The hole is there to prevent an air lock in the pump which would prevent it from moving water.

If the water trapped in the vertical run of the discharge pipe is returning to the pit once the pump shuts off the problem is the check valve is not holding or the hole is on the wrong side of the flapper assembly. Did the check valve come with the unit? If not, you will need to fix it if you can or replace it.

If this answer does not fix your problem, please comment with additional details prior to rating the answer. You may also contact me thru our website at www.arrowpools.net. Positive feedback is appreciated once your problem is solved!

the float will only work when the pump is running

Common problem with the Equinox with varying degrees of ocaisional poor starting.. There was a recall and TSB on some Vin numbers for a bad computer, and also some that needed the computer software reflashed.

take screws off the screen on the bottom of pump.....clean well

The Simer brand of submersible dewatering pumps rely on being fully submersed in water for proper cooling and for the seals to remain water tight and effective.

According to the manufacturer, there is no oil used in the pump, other than a very small amount that was used in assembling the pump at the factory, so you shouldn't oil the pump, but rather follow the recommendations as to making sure the pump is installed properly.

Here's the owners manual for your particular pump (Model #2300) so you can check the troubleshooting FAQ's and so you can also contact the manufacturer, should you need replacement parts or need to make a warranty claim, etc.

You will probably need to change your start capacitor if this is an induction motor.Please come back to me if you require further assistance

Remove "Door Ajar" switch. Clean the switch and use a graphite type lubricant (I recommend "Dry-Slide") to lubricate the actuator on the switch. Reassemble the switch.

The switches are located inside the door panels, attached to the catch mechanism.

1) Remove interior door panel.

2) Using a T-27 Torx driver, remove the 3 bolts holding the catch in the door.
2a) The door ajar switch is the only part on the mechanism with the 2-wire harness.
2b) The switch is located at the rear catch for the sliding door.

3) Using a small flat screwdriver, gently lift the black tab on the catch mechanism and rotate the switch to remove it from the catch assembly.

4) Using a rag, clean the small round actuator and apply a small amount of graphite lubricant to the actuator and work the switch so it moves freely.

5) Reassemble the catch and the door.
