Unplug the unit. The E90 code on the intex spa is due to a dirty water flow sensor. Remove the control panel and all the screw holding the casing on. In the white plastic piece on the discharge, top hose, you will see a silver nut with a black wire coming from it. That's the sensor. The black wire is plugged into a white wire, carefully unplug it and unscrew the sensor. Clean it good and blow out the hole it goes in. This will fix the code and you will be back in business!

If this is an outdoor spa near trees, its almost a guarantee that the impeller is blocked with debris (pine needles can cause this in a hurry)

If the impeller is clean of debris and this is still happening, replace you pressure/flow switch.

your sensor is not functionning , your hut tub runs for too long , is you filter clean ? It scould be a low flow of your water through the heating element, but you would have noticed that.

Blade valve is the best part for this if there is enough room to fit it in. Be sure nothing else is in the way before putting everything back together. Good luck, Tim

That is because it is not there and does not exist. You will need to have a switch on the electrical connection and incoming power.

Thank you for posting your question here on Fixya.com.

Page 43 of your manual, found here suggests both E05 and E06 errors mean the issue is related to "...(the) fuel supply, thermal regulator, check for correct orifices, etc...". It also touches on the possibility that if the unit was converted from NG to PP or vice-versa that the orifices are not correct.

Start with these two areas...if you need additional assistance please comment to this answer with details from what you find while checking these areas and I'll try and help you from there.

If this answer does not fix your problem, please comment with additional details prior to rating the answer. You may also contact me thru our website at www.arrowpools.net. Positive feedback is appreciated once your problem is solved!
