That is the same order this repair runs in, and it is worth saying that our page and the maker’s manual agree, because plenty of sites publish a meaning for a code nobody documented. ### Before you book Take the filter out, wash it, and clear the sump underneath it by hand. It is designed to be removed without tools and a real share of these calls end there. If water sits in the bottom after that, it is worth a visit. ### What is included The whole drain path checked in order, the filter housing and sump cleared, the part where there is one, the labor, and a full cycle run and watched to a dry tub. **Exact cost is confirmed after an on-site diagnostic.** What moves this figure Filter, drain hose, air gap, disposer connection, pump F2 is the maker's own code for a machine that will not drain A large share end in the filter housing How far along the path the blockage is Filter housing, sump, hose, air gap, disposer knockout. They run cheapest to most involved in roughly that order, and the diagnosis follows the path rather than opening the machine first. Whether a disposer was fitted recently The single commonest cause of a dishwasher that has never drained since a kitchen change is a new disposer whose inlet plug was never knocked out. It is a five-minute fix and it is checked early for that reason. Pump or blockage A drain pump that hums and moves nothing is usually obstructed rather than failed. It is cleared and tested before it is replaced. What has been through it Glass, seeds, labels and grease behave differently in a sump, and it changes how long the clearing takes. Say what happened if you know. The code that names this repair These machines publish a real error table, which almost nothing else on this site does.

Exact cost is confirmed after an on-site diagnostic. ### There is water in the bottom after every cycle. Is that a pump? Often not. A small amount of standing water is normal by design; a full inch is a drain restriction, and the filter and sump are the first place it lives. Clear those first — it is free and it frequently is the answer. ### It says F2. What does that mean? The maker's own table gives it as the machine being unable to discharge water, with the discharge hose and the filters named as what to check. That is a documented meaning rather than our guess, which is not true of most codes people search for. ### It started right after we had a new waste disposer fitted. Related? Almost certainly. A new disposer ships with the dishwasher inlet plugged and the plug has to be knocked out during the install. If it was missed, the dishwasher has had nowhere to drain since that day. --- **[Read full article: Dishwasher drain & filter repair cost](https://bertazzonimiami.support/repair-cost/dishwasher-drain-and-filter-repair/)**
