John for Model Number SHSM63W52N/01 This is a follow-up comment and question to my post a few days ago The suggestion to look at the control module as the source of the problem is reasonable, however, I did replace this already as the first step in my repair efforts several months ago. So, before spending that money again, I am looking for any other possibility. Since the E:08 may indicate a water problem, I have tried running the dishwasher with all spray arms and tubes removed. I find that with all spray components removed, the dishwasher heats the water to 160-164 F and gives an error code E:00. With the tube to the upper spray arm reinstalled, but not spray arms, the error code E:08 returns and the water does not heat. With the upper spray tube removed again and with the lower spray arm installed, the water heats and and E:00 is displayed. I have gone back and forth 4 times now with and without the upper spray tube installed, and the dishwasher works normally every time when the tube is removed. I cannot find any obstruction in the tube. It is very easy to blow air through each of the tubes going the upper spray head and the upper spray arm. Additional point & question: Since it may be a water flow problem, is it possible that either the pump is not pumping as well as it should, but well enough to operate without the extra resistance of the upper spray arm tube? Likewise, if the alternating water distributor aperture plate is not properly oriented, could the water pressure be reduced enough to give the same behavior? The water distributor plate can be seen to be blocking all ports when the dishwasher is off. Contrary to this, a new one that I have on hand has the lower port position open in the unpowered state.
Answer John, the first check to make is the water level in the bottom of the tub after a fill cycle, start the dishwasher, let it fill and wash for 3 to 5 minutes, unlatch the door, and remove the lower rack, the water level should be 1/2 to 3/4 in. deep (level with the top of the course filter opening). E:08 no load in circulation pump / Heat pump detects too low of a water level in the sump. The E:00 code indicates no failures logged in the control board chip. The low water level would account for the other maladies you described. Thanks, Read More... Answered by AppliancePartsPros.com | Wednesday, March 17, 2021
