You need to be sure you are in Standard mode. If the spa is in economy mode it will only heat up during a filter cycle twice a day and this will not allow the spa to heat properly. You should see the word standard in the 880 topside display if good if not press the mode button. From there you can try resetting the spa by turning off power for 10 minutes then reboot to see if it was just a fluke.
