How do i replace the top clip on the ec 40


You have to compress the top plate AFTER BEING CERTAIN the bottom plate has the flex tubes fully installed on the correct side of the plate and the plates are aligned. The shaft groove will be just below the plate surface prior to pressing the top plate down and once down you can place the e-clip into the groove to secure it.

Here is a link to the hayward manual. Be sure to follow the pre-coating insturctions carefully.
Use only the swimming pool grades of
diatomite, such as:
CELATOM . . . . . . . . . . . Eagle-Picher Industries, Inc.
AQUA-CEL . . . . . . . . . . Johns-Manville Products Corporation
DICALITE 4200 . . . . . . . Grefco, Inc.
WITCO . . . . . . . . . . . . . Witco Corporation
The EC-50 filter uses a 5 lb. (2.3 kgs.) charge of diatomite (D.E.)

Here is a link to the hayward manual for a EC-50 I think its almost the same as the EC-45

I have the Hayward EC-40 Filter, my problem is the DE is getting into the pool. What would cause this?


Broken/torn grid, o-ring bad in the housing by the grid assembly or grids not in manifold properly. Backwash, open the filter, remove and inspect the grids (the plastic bases too).

Hayward eC-40 pump losing pressure very fast


A better way to clean the filter tubes in the EC40 is to remove the filter tube assembly and soak it in a 5 gallon paint pail that is filled with a solution of water and a 20% muriatic acid, available at hardware and home center stores. Be very careful handling the muriatic acid. Don't splash it around.

Mix it in a 1-to-1 ratio with water and soak the assembly for at least 8 hours. Keep the soaking pail out of the reach of kids and animals.

Remove the assembly, properly dispose of the acid mix and refill the pail with clean water. Soak again for 3 to 4 hours, then reassemble your filter.

Some pool guys say it isn't necessary to soak the tubes in clean water because the muriatic acid will not harm the pool water and will reduce the pH if it's too high. I've always soaked them to be safe.

This is a link to the Hayward manual that describes the process:

Hayward pump wont prime. air bubbles coming back into pol with water and de


You have a leak, if DE is getting back in pool your filter is either dirty and needs to be taken apart and throughly cleaned, or you have a ripe in one of the DE cells. The pump not priming is a leak somewhere before where water enters pump. Could be a bad o-ring in a valve. Hard to tell what is is without troubleshooting, piece by piece. I would start with cleaning Filter first.

Jet Pump stops after three starts of 20 minutes each and it doesnt want to start back again until the next day or after a few hours


check motor with hand after it stops for excessive heat. Thermo coupler shuts motor off if overheating, to protect windings. Bad motor bearing can cause overheating, if so should hear bearing noise when running.
Also check start capacitor, by removing and checking with ohm meter, or plug in oposite terminals of capacitor to charge. Place rubber glove on hand, and contact two oposite terminals with screwdriver should produce a small spark.
