Chlorinator esr 160 pool pump

SOURCE: Reduced circulation/backwash (sand filter)

check your pool pump by putting the valve in recirculate mode.If flow is a problem it may be a clogged impeller.

SOURCE: Using a swimming pool filter system to 'vacuum' the pool floor

i am assumming that you have a sand filter,to clean your filter, 1st put it on backwash and watch the little glass bowl till it run clear,45 sec. or so then turn off power, turn valve to rinse, turn power on. watch little bowl till it runs runs clear 30 sec. or so.to vaccam turn handle to waste turn power on. hope this helps

SOURCE: salt water pump worked good now will not go to cholorine, no code

I EAS GOING TO UPGRADE TO A SALT PUMP FOR OUR POOL LET ME DO SOME RESEARCH ON THIS FOR YOU

SOURCE: 1/2hp Hayward Pump for existing inground pool

you will be fine with the 1/2hp. The Hayward will move quite a bit of water as well. It may not move as much water as the 3/4hp but it's very close and the 1/2hp will cost a little less to operate so if anything, you may just have to run it for one additional hour per day to compensate. You will be surprised how much water a 1/2hp will move. The only issue with smaller pumps is if you have pop-up cleaner heads or a suction driven automatic cleaner such as a kreepy krauly, however, if a 3/4hp will run it, a 1/2hp will run it as well. You can install a larger motor on the super pump but it will not move more water unless you upgrade the impeller as well. Just make sure you don't use a bigger impeller than what the motor is rated for because it will strain the motor and cause it to overheat. Hope this helps.

Testimonial: "Great. Thanks for the quick feedback. I look forward to saving a few $'s this year operating my pool. Cheers!"

The most like problem is the chlorinator has stopped working.
Most salt water chlorinators have a circuit breaker which cut power to the electrolyte cell if there is an overload or short condition. Check the circuit breaker, reset is necessory.
The other possible problem with the chlorinator is that voltage/DC current is supplied to the electrolyte cell via a low voltage transformer and rectifying circuit. if these components are faulty then the electrolyte cell will not produce chlorine. When the electrolyte cell is working normally you can see tiny bubbles of hydrogen and oxygen coming off the cell.
