Realize I can't use the oven to heat my food as there's a chili cooking in it at low temperature. Figure I could make myself an omelette. Frying pan needs to be washed. Turn to the sink - it's full of dishes. Ask our eldest if he can load the dishwasher (it's his chore and he should have done it earlier in the day), am informed that the dishwasher isn't cleaning properly, though nobody told me. Look for the dishwasher manual to check its maintenance instructions. The manual is more of a pamphlet and says (paraphrase) "if these instructions don't work check the full user instructions".
