Coleman Hot Tub Error Codes

There may be a number of reasons why your heater pump is displaying an error code. The following is a list of error codes, the reason behind them and how they can be solved.
Coleman Spas are programmed to filter twice a day. The first cycle starts six minutes after the spa is turned on, and the second cycle runs 12 hours later. The default filtering is for two hours, but you can change this to suit your needs. Filtration time can be anywhere from one to six hours. SN, Sn1, Sn2 Sn3, HL, E1, E3, Prh, HtS, Blinking Lights; Hi Limit Sensor Failure. These error codes are similar to the ones previous, however we will be looking at.

DescriptionCauseSolution
Sensor ErrorThe water flow sensors' flags didn't come back into the correct position.Unplug the pump unit, lightly strike the side of it and then plug it back in.If the unit does not respond, try rolling the pump unit on its side in order to shift the sensor placement.
Water Flow ErrorElectrical issue. Can occur when the spa is not plugged into a mains socket. May also be an issue with the RCD socket.Plug the pump unit directly into a mains socket and not into an extension lead.
Debris Build UpIssue with water flora sensors due to debris build up.Please follow the backwash procedure in the video here

DescriptionCauseSolution
Water Flow ErrorThe stopper caps are still inside the spa.Remove the black stopper caps from the inside of the liner before heating, filtering or running the bubbles on the spa. If you are unsure how to remove them, please refer to the assembly section within the Lay-Z-Spa owners manual.
Filter cartridges are dirtyRemove the filter cartridge from the filter housing and check it is clean. Please make sure the new filter is clean and dry before you install it.
Filter housing is restricting flowRemove the filter housing from the liner and check the black membrane inside. These should lie flat inside the housing. If they are ok, continue to run the spa without the filter cartridge attached and see if the error code persists.
Ensure that the debris screens are clear of debris.
Pipes within the liner are kinked or bent.Disconnect the pump and check the pipes inside the liner. You can manipulate these with warm water to return them to the correct shape.
Washers perished inside pump couplingsDisconnect the pump from the liner. Check the condition of washers inside the couplings on the pump. We would suggest backwashing the pump to clear any debris. If the washers are perished you can purchase spares from the Lay-Z-Spa website here

Not grounded/earthed correctlyAn issue with your power supplyRemove any extension leads, we do not recommend the pump is run on one of these. Also try the pump in an alternative socket. If the issue persists, please contact us for further advice.
Backwash ProcedureAttach the stopper caps to the inside of the liner and then remove the Lay-Z-Spa pump unit from the liner (you can do this by unscrewing the 3 couplings ‘A, B and C').
Using a hosepipe, flush water backwards through the pump. Water should go through pipe ‘B' and come out of pipe ‘C'.
After a few minutes, flush the water in the opposite direction for about 2 minutes (through pipe ‘C' and out of pipe ‘B').
If you have a Hydro Jet Lay-Z-Spa, unfortunately, the backwash procedure will be a little tricky. These are not constructed like the other models of the Lay-Z-Spa. please contact us
