The rinse light is telling you the resiviore is empty and should be refilled the sanitize means that option is choosen try resetting options

sometimes it is because of a stuck button, push-tap the buttons
and see if it does anything otherwise sorry.

When this happens with my dishwasher it usually means that the drain is clogged with food/debris.  To fix 1) remove bottom dish rack from machine 2) using a small cup, scoop out as much water as possible 3) remove inlet drain cover and unsnap the plastic insert and remove 4) rinse the plastic part and reinstall 5) start machine 6) if light still flashes, repeat steps 3 4 and 5 and restart

Hold the Rinse button for 5 seconds to reset.

Try using a cycle that doesn't heat the water. (Quick cycle?) Using high heat rinse or sanitize will stop the timer while it heats the water. The sensor may be bad.

I may have fixed my similar problem- I opened up the machine to get access to the control panel as tech17 advised- then in addition to disconnecting the mylar ribbon, I disconnected all the connections to the control panel.... keep in mind to ensure not to confuse any of the connectors you disconnect. Running a cycle at this time... seems as if working.. can't tell if water is running or just the motor- -- HA! -- i confirmed no water being pumped in.... We then found a float switch (Item 30 on schematic) that got loose from its casing on the front interior right lower side... we put that switch into its proper place and now ALL IS WELL!!!! Yippee!!!

I had the same flashing light problem first the normal wash flashing light then the others. I tried shuting of the breakers but nothing. I tried resetting the panel by pushing normal wash and heated dry simultaneously and nothing. So I took the six screws holding the front panel out and unplugged the ribbon type wires and plug and unplugged it several times to help make a better contact and I was able to get it to work right away. This may not work for all but I worked for me. It is very easy to do and it's worth a try if you're having the same problem. It took me less then 10 minutes.

I am having the same issue as described above. I think it is either the timer, thermostat (temp assure), or thermostat (temp boost) that needs replacing. The dial gets stucks in both the wash temp boost cycle and rinse temp boost cycle. However, I don't have a picture of the temp assure or boost part. Does anyone know how to fix this? Thanks. -Bill
