SOURCE: If my hayward pool vac (AquaBug) is always

Probably go for the 2 speed, manufacturers often embellish on the hp ratings of pumps, you will definitely see more energy savings from a 2 speed. Just stay away from hayward, easy to work on for service tech's for break alot. Go with Pentair or Jandy they are worth the money.

SOURCE: OP error code. What is wrong with my Hayward pool

OP is the error code for a faulty Temperature Sensor. Try replacing the Temperature Sensor. I have seen many of these units have the wires chewed up by mice, etc., so you may want to check the wiring for any damage.

HF code on hayward 200fdn pool heater?replaced gas valve still have same code.What now?


HF
Flame present with gas valve "OFF" error
If flame is sensed with the gas valve off the control will go into lockout. The blower will run until error condition is corrected. When corrected, control will run blower for 5 s then automatically restart after 2 minutes.
the error might be caused by a faulty flame sensor. i have heard of this happening the other way (carbon blocks sensor causing no ignite)

Error codes on Kenmore Elite washer


F11 is a serial communication error. Communication between the main board and the motor control board is not being sent correctly. This could be a bad main board, motor control board or motor itself. The testing can get pretty involved. Try putting the machine in a self test mode and see if the error clears. Press Cancell, then by pressing the drain spin button once on the left side then move to the spin speed button the the right. Press this button until no-spin lights. Press the prewash button 4 times. C00 should appear in the display. Let it run it's tests, there will be 8 of them and end up on C08. If this doesn't work, it's best you wait for the service tech.


while F09 is the water pump. It usually means something is clogging it. Take the front cover off of the washer and the water pump is located right in the middle front. Unscrew the cover to the pump and make sure there is nothing clogging it.

Stops about half way thru cycle anf error code HF appears


F/H No water detected entering machine or Pressure switch trip not detected.
If after 30 seconds the control does not detect water entering machine and then valves will be turned off and the error code will be displayed.

Or

If the control has turned the water valves on and after 8 minutes the flow meter has detected 10.5 gallons of water passing through it, but has not detected the pressure switch trip, the valves will be turned off and the error code will flash.


Press PAUSE/CANCEL twice to clear the display. 
If there is no water in the unit:
1. Make sure that both valves at the water source(s) are turned on all the way.
2. Check for plugged or kinked inlet hoses or plugged screens in the inlet valves 
3. Verify inlet valve operation 
If there is water in the unit:
1. Verify Drain pump operation
2. Pressure Switch Hose is in good condition and properly connected to Tub and Pressure switch 
Verify there is not a siphon problem 
Verify wire harness connections to:Inlet Valves, Pressure Switch, Drain Pump, Flow Meter, and Central Control Unit (CCU) 
Check all hoses for possible leaks 
Verify pressure switch operation

Verify flow meter operation 
Verify CCU operation.
