Ours hummed and never filled. He tested the inlet valve, found it fine, then found the supply stop half shut behind the cabinet from earlier plumbing work. He opened it and checked the fill rate before leaving.
Dishwashers
Viking dishwasher repair
Panel-ready and stainless dishwashers. Drain and fill faults, heater and relay failures, blocked spray arms, door spring and cable wear, and boards after power events.
Circulation, drainage, heat and the door seal are the four things that can be wrong. Each is tested before a part is ordered.
Symptoms
What you are seeing, and what it usually is
Described from the owner's side. No invented error codes. Where we are not certain of a cause we say what we check rather than guess.
| Observed | Usually | The work |
|---|---|---|
| Dishes come out gritty or filmed white | A rinse that never reaches temperature, a detergent and rinse aid regime that does not suit the load, or upper jets no longer clearing the glassware. | Time a full cycle to prove the heater holds temperature, flush the arms jet by jet, and set a regime that matches how the machine is actually loaded. |
| Top rack not cleaning | Blocked upper spray arm jets or a split feed tube. The small jets on the upper arm are always the first to plug. | Remove and flush the arm, check the feed tube seal, verify pressure with the arm off. |
| Water left in the bottom at the end of a cycle | Drain pump obstruction, a blocked filter, or a high loop that has been knocked down under the sink. | Clear the sump and filter, test the pump, verify the drain hose route and the air gap. |
| Cycle takes hours and dishes come out cold | Heater element or heater relay failure. The control extends the cycle while it waits for a temperature it will never reach. | Measure element resistance, check the relay on the board, replace the failed part and time a full cycle. |
| Door drops open or is heavy to lift | Broken door spring or a frayed door cable over the pulley. Normal wear, worse on panel-ready doors carrying a cabinet front. | Replace springs and cables as a set, re-tension both sides evenly. |
| Dead panel, no lights | Control board or the door interlock switch. Boards fail after power events, which are routine in a metro with about 68 thunderstorm days a year. | Check supply, test the interlock, inspect the board, replace and advise on surge protection. |
| Leak at the bottom of the door | Hardened door gasket or a warped panel-ready door pulling the seal away at one corner. | Replace the gasket, reset the door alignment, run a full cycle with the machine on paper to confirm. |
Detail
How we approach it
The order a dishwasher gets diagnosed
Almost every dishwasher complaint arrives as one of three sentences: it does not clean, it does not drain, or it takes forever. Each of those has a check order, and following it is the difference between a part that fixes the fault and a part that gets fitted on a guess.
It does not clean. Flow first, chemistry second, parts third. We run a short cycle and open the door thirty seconds in to see whether both arms are turning under real pressure. If they are, the pump and the motor are fine and the fault is downstream: plugged jets, a split feed tube, a filter that has never been rinsed, or a load pattern that puts a tall item where it stops the arm. If they are not, the sump, the filter and the pump come first and nothing else is worth measuring.
It does not drain. Standing water at the end of a cycle is a drain problem four times out of five and a pump the fifth. Filter, sump, hose loop, air gap, then pump — in that order, because the first two are free and the last one is not.
It takes forever. A cycle that stretches and finishes cold is the control waiting for a rinse temperature it is never going to see. That is the heater or its relay, and it is measurable rather than debatable.
What a proper clean-out actually involves
When the machine is the problem, the work is worth describing, because “we cleaned it” covers everything from a rinse to a real service.
The arms come out and get cleared jet by jet, not flushed and hoped over. The sump and the filter come out and get stripped. The element gets checked for resistance and for anything baked onto the sheath, because a coated element still draws current and still cannot get the heat into the water. Then we run a full timed cycle and confirm the rinse temperature actually arrives, so the result is proved rather than assumed.
Then we tell you the interval to repeat it at for your household, based on what came out of the machine. A house that runs two cycles a day with heavy loads is on a different schedule from one that runs three cycles a week.
Genuine mechanical failures
Drain. Standing water at the end of a cycle is a drain problem four times out of five and a pump failure the fifth. The order of checks is filter, sump, hose loop, air gap, then pump. Plumbers get called for this constantly when a filter clean would have done it.
Heater. A cold, endless cycle is a dead element or a failed relay on the board. The control keeps waiting for a rinse temperature it never gets, so the cycle stretches instead of stopping.
Door. The door is counterbalanced by springs and cables for a specific weight. On a panel-ready machine that weight includes your cabinet front. When a cable frays or a spring relaxes, the door drops. It is a routine part, and both sides go in together so the balance stays even.
Boards. About 68 thunderstorm days a year here. A dead panel after a storm week is a board or an interlock, and a whole-house or panel-level surge device is worth more than the repair.
Access. A dishwasher comes out on its own feet, but the supply line, the drain and the power connection are all behind or under it, and on a panel-ready machine the cabinet front has to come off first. We protect wood and stone floors before anything moves.
The one thing worth saying about the water
Tap water here is mineral-rich, and a machine that heats and evaporates it several times a week will eventually show it — as film on glassware, as narrowed jets, and as deposit baked onto the element. Clearing that is part of the repair when we find it, and we will tell you the interval to repeat it at. We do not sell or fit water treatment, so there is nothing in that advice for us either way.
What to check before you call
Two things you can do in five minutes that occasionally save you a visit.
Pull the filter out of the sump and look at it. On a machine that has never had the filter cleaned, the mesh can be solid enough to stop the drain on its own, and the fix is a rinse under the tap.
Then run a short cycle and open the door thirty seconds in. If the wash arms are turning and water is hitting the top rack, the pump and the motor are fine and the problem is downstream. If the arms are not turning, note that when you book, because it points at a different set of parts entirely.
Finally, look under the sink at the drain hose. It should rise to a high loop or an air gap before it drops into the disposer or the standpipe. When somebody stores cleaning supplies under there and knocks that loop down, the machine siphons and leaves water in the bottom. It looks exactly like a failed pump and it is free to fix.

Questions
Asked on most of these calls
Why is the bottom rack clean and the top rack dirty?
That split is diagnostic. It means the pump and the motor are working and something upstairs is not getting flow: plugged jets on the upper arm, a split feed tube, or a tall item on the bottom rack blocking the arm from turning. It is rarely a failed pump.
Is it worth repairing a dishwasher over ten years old?
Depends on the part. A pump, a heater, springs and a gasket are all worth doing. A control board on a machine that age is a conversation, and we will give you the number before you commit.
Why does my panel-ready door feel heavier than it used to?
Because the springs have relaxed. The door was balanced for the weight of your cabinet panel. When one spring tires, the door drops. We replace both sides together so it stays balanced.

Where This Comes Up
Areas where we see this most
Ranked by how much this appliance's failure pattern overlaps what the housing stock, the exposure and the age of the equipment there actually do. 40 miles by road of Fruit Cove, St. Johns County.
The building here is recent and the installs are sound, so access is rarely the constraint. Power events and tightly built houses account for most of what we are called out for.
Our dispatch base and the shortest drive we make. The housing along the SR-13 corridor is 1990s and 2000s, so most of the equipment here is now at the age where the electronics matter.
New construction throughout, so access is rarely the obstacle. What we get called for here is wear parts reaching their age, and control boards after power events.
Two different service problems in one city. Modern built-ins on the Southside, and 1900s to 1930s kitchens with undersized openings in Riverside, Avondale and Ortega.
Reading
Background on this fault
Cabinet openings, countertop overhangs, rails, weight and the connections at the back decide how long a built-in repair takes. None of it is visible from the front, which is why we look at the installation before quoting.
Surge damage is rarely instant. A board takes a hit, keeps working, and fails days later. Understanding that changes what a technician should test first and what protection is worth buying.
Two appliances with the same model number can take different parts depending on when they were built. This is how we identify the right one, what we carry, what has to be ordered, and how long each of those honestly takes.

4.8 out of 5, across 47 customer reviews. Every one is a single visit, in the words of the person whose kitchen it happened in.
The lower arm turned but nothing on that rack came out clean. Its pump impeller had shed a vane. A new pump went in, and he ran the machine with the baskets pulled clear so I could watch water reach both arms.
Ours leaked at the lower corner and had marked the floor before we noticed. He replaced the door seal, dried and checked the base tray, and pointed out that the machine had never been levelled properly.
