Hi i have a monarch spa xS3000 recently after emptying to clean i refilled and error 4 kept appearing. Turns out heater was damaged..Replaced with new one and refilled again and same error 4 apperars .has no airlock .

Hi, this is John the Hayward tech. If you are now seeing the #4 fuse go that is on the low voltage side. I would guess the main circuit board. I left a manual on your other post.

You have a bad thermistor. The heater thinks that water temp is over 114 degrees.

Error: "Invalid Toner Cartridge"; Error: "Invalid Refill"; Message: "Change Cartridge"
Solution
One of these error messages may appear on the printer display immediately after or shortly after a new toner cartridge is installed into the printer. Note: This may not be specifically a toner cartridge problem; the error may be due to a stuck cover open switch on the printer.

To see if the cover open switch is the cause of this problem, open the top front cover and observe the message on the printer's display panel. The display should read Close Door or Insert Cartridge.


If this message is not displayed, the top cover open sensor and switch will need to be replaced. In addition, the printer may have damaged the new toner cartridge. If the cover open sensor is not operating properly, a new cartridge can be incorrectly flagged as a refilled cartridge by the printer. If this happens, the new cartridge will continue to cause an Invalid Refill or Invalid Cartridge error even if you try reinstalling it or installing it into another printer. If this should occur, please contact the point of purchase of the cartridge to find out how to get the cartridge replaced.

Caution: If the cover open sensor is not operating, do not install another new toner cartridge until you have completed the directions below. Inserting another new cartridge can cause that cartridge to stop working as well. Should this situation arise, please take the following actions:


Place the original working cartridge (the empty or near-empty one) back into the printer. This should clear the error message.

Turn the printer off. Doing this will disengage the cover open sensor.

With the printer switched off, open the top lid and remove the old toner cartridge.

Now replace the old cartridge with another new Lexmark toner cartridge.

Power the printer back on. The printer should now read this cartridge as a newly installed toner cartridge and the error should be cleared. The printer and toner cartridge should function properly now, but the top cover sensor on the printer will still need to be replaced.

If your printer is still under warranty or covered under a service contract, please contact Lexmark Technical Support or your service provider for further recommendations and instructions. Until you can get the cover open switch replaced, remember to have the printer powered off whenever you replace the toner cartridge.

If the top cover switch appears to be working fine, or if you have followed the above steps and your printer continues to post an Invalid Toner Cartridge or Invalid Refill error, make sure you are using a new original Lexmark toner cartridge. A toner cartridge remanufactured or refilled by a third party can cause this error.

To help identify a refilled cartridge, look for the yellow label attached to the toner drum and the body of the toner cartridge. If this is damaged or removed, the cartridge may have been refilled.

If you are using a third-party refilled or remanufactured toner cartridge, it is recommended that you install a new Lexmark brand toner cartridge. Lexmark cannot guarantee the compatibility of any third-party toner cartridges with our printers.

OR

1 Switch on the Lexmark X83 printer.

2 Lift open the cartridge door at the front of the device, below the scanner unit. The printer automatically moves the cartridge carrier to the correct position.

3 Pull each ink cartridge toward you to unclasp it from the carrier. Lift the cartridge out of the cartridge carrier.

4 Clean the copper contacts on the bottom of each cartridge with a clean, dry lint-free cloth. Use a gentle, circular motion to clean the contacts.

5 Insert the ink cartridges back into the cartridge carrier. Push back firmly on each cartridge until it snaps into place.

6 Repeat each step in this procedure again. Close the cartridge door.

Not likely. The only reason the breaker trips is if there is a fault to ground or too much load on the breaker. If say you over filled the tub and components got wet, that would cause a ground fault.
If not I would call the supplier and request another service call to determine the problem

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.

this may be for two reasons first the water is going to slow make sure filter is clean and either the water inlet plump incorect or the valve assembly is damage and need to be replace the high limit is letting you know the temp is getting to hot inside the heat exchanger

Hi Lisa,

If it responds ok with the old cartridge then the problem is with the cartridges' chip not the printer. Probably the manufactor has a problem with certain cartridge chip (contact them!). I would suggest to use the original at the problematic spot if it works without a problem.
