Turn your dishwasher back on.

This may not fix it permanently, but the same procedure will work again and again.

If someone a permanent fix please share! I suspect a defective float switch (Bosch part #165256) but thee fact that my DW works for a couple of cycle before the issue coming back makes me a little skeptical.

On this dishwasher you should check on the right side for a leaking wash motor pump assembly
