SOURCE: Hayward H250 giving me a "LO" error code and does not turn on.

9 times out of ten this means that you have a faulty water pressure switch. It could also be a limit switch, or air pressure switch. Make sure the filter is cleaned, and all valves are in the correct position. Once you are CERTAIN that water is flowing through the heater, you will need to short each individual component to find the faulty one.

SOURCE: Error code LO

Is the heater installed indoors?? if so you'll need a vent pressure orifice kit.
if not check your water press. (below 18 PSI on filter) Place filter on "recir" if it fires and stays on . it's the pressure.
check to see if all connections a set tight hi-ltd switch wire harness etc.

One of your limits is not working or not wired up. An easy way to check the limits - Water pressure switch, Hi limits, air pressure switch all of which have 2 wires going to them. Unplug one item and connect the 2 wires together ( paper clip works fine ) Then retest, if problem does not go away remove paper clip and reconnect wires and move to the next limit. The limits are located in the black plastic header. Always make sure water is flowing through the heater at all times while checking the limits.

Low Flow errors are not necessarily real. They can be caused by improper adjustment or a defect of the pressure switch. Locate the pressure switch. Verify that the "switch" makes contact. Adjust the dial, reducing the distance the switch has to travel to engage. This will effectively lower the operating pressure required to operate. Keep adjusting until the unit stays on.

Duet. What does F8E1 code indicate needs to be done to restore operation?


Check out the Link and the info below.
Question: Front Load Washer - Error Code - F8 E1 or LO FL Answer Product Symptom:
Front Load Washer - Error Code - F8 E1 or LO FL


F8 E1 or LO FL Code in display:
No water detected entering washer after 13 minutes, the pressure switch input has not been detected.
If the washer has an F8 E1 error or LO FL error, the door will be locked, and the control will be unresponsive. The washer will start a drain routine which takes approximately 8 to 10 minutes, during which time the pump will run continuously. The control will not accept any input during this time. Please wait 10 minutes before trying to perform any functions.
Check the water supply:

Turn on the water. Check the household water supply to see if the hot and cold water faucets are turned on. Make sure to open both faucets completely for proper fill.

NOTE: Both Hot and Cold water must be supplied to the washer.

Whirlpool recommends that appliances be direct connected to the water supply for optimum machine performance.
If a "flood saver" device is being considered:
  • Check with the manufacturer of the device to ensure it will not affect the performance of the appliance.

  • Whirlpool has experienced that "flood safety" devices can interfere with the performance of the appliance. Whirlpool typically does not recommend these devices.

Error code (LO)


Could be either the pressure switch(tells the heater that there is suitable amount of water flowing the startup the ignition), hi limit switches, or low vent pressure(if you have a exhaust fan installed for the model. Easiest thing to try is to give the pool filter a good backwash. If this doesnt solve the problem, than the above electrical components need to be looked at and singled out

Lo error showing and it kicks off about every 6 minutes


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


A 'LO' error code for a Hayward heater is a limit string open error. If the limit string opens the heater shuts down and goes into lockout. Automatic restart is 2 minutes after the error condition is corrected and the limit string closes.


The limit string is a series of switches designed to turn off the heater if air or water temperatures exceed a safe operating limit.


The problem may be faulty a switch(es) but is far more likely to be a system condition the switches are reacting too that needs to be corrected. Low flow of combustion air due to obstructions around the heater or the vent; low flow of water through the heater allowing too high a water temp; Poor venting or sooted-over heat exchanger causing flame rollout. These are all conditions that should be eliminated if they exist.


If you are not familiar with these switches or the conditions described you may want to consider calling in a professional. Hayward can refer you to someone in your area who is. Call Hayward at 908-351-5400 or try the website locator found here.

Getting LO error


Lo is an error code dealing with the safety loop, hi limit switches, water pressure switches. Check for continuity and the wiring between the hi limit switches and the water pressure switch. Also, check to make sure the filter is clean and the pump basket is empty. These also can cause a low flow situation that will cause the pressure switch to not close properly.

On occasion, my furnace will not kick on at


If your Rheem furnace is less than 10 years old, it may store an error code to help you figure out if it is the furnace or the thermostat. Look at the circuit board for a blinking light. If you have to remove the panel that opens up the door safety switch, it will erase the code. Look for a small viewing port. Next time the furnace fails, prior to doing all the things you did last time, look thru the viewing port to count the number of blinks. Once you get the number, open the cabinet and on the wiring diagram glued to the back of one of the panels'\; there will also be an error code chart. It may give you a starting point where to look. If you have no error code, chances are that your thermostat is freaking out or has a bad connection. Hope this helps.
