SOURCE: what is a limit string error locking out the
The limit string or saftey circut as it was called for years till it wasen't confusing any more is simpley the itims the heater goes through to be shure it is safe to light. This starts with the presure switch and is most often the fault. If you don't have enough water pressure than the heater won't fire. Check your baskets, filter and pump impeller. Then the high limits but these fail for the same reasons. Your thermostat is the next thing in line and the temp sensor or thermistor. (more new names) and on some models their was a flame roll out switch in the bottom front of cabnet. Your problem will be in one or more of these itims and you can usually check them by simpley jumping them with a small wire. But they do a job so do not leave the wire in place to make it work. Good luck.

The code is "PS" for Pressure Switch and means there is insufficient pressure to operate (low flow) or the switch itself is bad.
