Viking Dishwasher Not Filling
The programme starts and the machine runs, but no water goes into the tub.
| What you can see | What it usually is | Whose job |
|---|---|---|
| The programme starts and runs but the tub stays dry | The screen behind the fill valve has silted over and is passing next to nothing | Ours |
| A faint hiss at the machine and still no water | The valve is being told to open and is opening, but nothing is getting through what sits behind it | Ours |
| Nothing at all — no hiss, no movement | The small tap on the supply under the sink has been shut, or shut most of the way, since other work was done in the kitchen | Yours to find and open |
| It takes a little water and washes badly | Enough is getting past the deposit to let the cycle begin, but not enough to fill the tub properly | Ours |
Every gallon this city sends up the pipe carries dissolved mineral, and the mesh behind the fill valve is the first thing narrow enough to catch it. So a tub that stays dry is far more often a silted screen than a dead valve. Viking Repair Denver clears and tests before it replaces anything, on (303) 729-0972.
A dishwasher takes its water through one valve, so a fill fault is either that valve or something sitting in front of it. There is not much else on the inlet side to go wrong.
Why the fill side silts up first
Mineral drops out of solution wherever water slows down or turns a corner, and behind the fill valve there is a mesh whose whole job is to keep grit out of the works. It is by a long way the narrowest thing the supply has to get through. It does not block overnight either. It glazes over across a winter or two, until the tub fills a little later, then a little short, and then not at all — which is why so many owners date the fault to the morning it finally stopped rather than to the months it spent getting there.
What comes off the van
A screen, usually, and a length of hose. The valve itself gets tested before anybody condemns it, because a clean valve that opens properly is worth keeping, and a new one fitted behind a blocked mesh will fail in precisely the same way within the year. Where the deposit has worked past the screen and into the body of the valve, the valve is replaced. Where the machine is simply being starved by a half-closed tap or a hose that has been kinked against the cabinet back, nothing is replaced at all and the visit is a short one.
What to try before anyone drives over
- Find the small tap on the supply under the sink and make sure it is fully open. Anything left half-shut after other work will starve the machine.
- Run the hot tap at the sink for half a minute and watch the flow. A weak stream there puts the fault in the house rather than in the appliance.
- Start a programme and put an ear to the front of the door. A hiss with no water arriving is a different fault from complete silence.
That is as far as it goes without tools. If it is still wrong, call Viking Repair Denver on (303) 729-0972 and say whether you heard a hiss when the programme started — it is usually enough to know which part is coming on the van.
