dishwasher: the dishes come out wet at the end of the cycle

Three of the five things behind wet dishes cost nothing to fix and only one is a part: rinse aid, a load made of plastic, and a machine that dries by condensation by design all look exactly like a failed element. Rinse aid has run out: 5 minutes, no part needed [S1] — the first of 3 causes on this page that need no part at all. On a dishwasher the complaint is the dishes come out wet at the end of the cycle, and it arrives in these words: everything comes out wet at the end of the cycle, the plastic items are soaked and the glasses are dry, it used to dry and now it does not, there is water pooled on the upturned bases or the dishes are wet and the plates feel cold. Until that check comes back clean, every price below is premature — the completed repairs behind this symptom run $294–$514 [S1], against a replacement from $600.

The first of the three things the source separates from a failed part, and the one that gets mistaken for a fault because it happens gradually: rinse aid breaks the surface tension so water sheets off instead of sitting in drops, and when the reservoir empties the load comes out wet while nothing has broken. Free to check, and it is the reason the page opens here rather than on the element - the source's own warning is that this is where money gets wasted.

The cause that explains the pattern people describe without realising it is the diagnosis: plastic has almost no thermal mass, so it is still cool when the drying phase ends and the water on it does not evaporate, while china and glass in the same cycle come out dry. A load of plastic containers is not a machine that has stopped drying, it is a load with nothing in it that can hold the heat. The free fix is to add a couple of ceramic items and see whether the result changes.

The second thing that is not a fault, and the one that matters for a large part of the European market: many machines - Bosch and Miele among them - have no exposed heating element, and dry by condensing moisture onto the cooler stainless walls and draining it away. That design leaves more water on plastic than an element does, by design. The source is explicit that this is the case where the answer is the machine's design rather than a repair, and the check is whether there is an element in the base at all.

What a technician actually does

The one cause on this page that is a part, and the reason the symptom is easy to misread: the element does two jobs, heating the wash water and drying the load at the end, so a failing element shows up as wet dishes first and as dishes that no longer come out clean a few loads later. The source gives the test that separates it from the free causes - the dishes are wet and the wash water is cold to the touch mid-cycle - and the second signal is that cleaning has quietly got worse at the same time.

hard water scale shortening the element's life [S1]

medium likelihood moderate $294–$514 installed about 120 min

it used to dry and now it does not

The cause the source says changes the repair rather than the symptom: in hard water the element collects scale, scale insulates it, and an insulated element runs hotter and fails sooner - so the same repair is needed more often, and a household that has replaced one element is likely to replace another. The practical part of the source's note is that the drying complaint and the hard-water complaint arrive together, which is why the scale question belongs in the diagnosis rather than in the maintenance advice at the end.

Repair or replace?

Check the free causes before anything is priced, in the order the source lists them: is there rinse aid, is the load mostly plastic, and does the machine have an element at all. If the dishes are still wet and the wash water is cold to the touch mid-cycle, the answer is the element at a $360 median - and that is a repair on any machine, because $294-514 against a $600-1,200 dishwasher is not close. [S1]

the ten-year line used across this site's dishwasher guides, with the half-of-new-price rule applied to a $600-1,200 machine plus $150-250 of installation and haul-away; on this symptom the arithmetic rarely comes up, because the free causes and the element both sit far below that line
