Viking Built-In Dishwasher Code Fill too Fast Error (4-5): tub filled quicker than expected

What Fill too Fast Error means

Fill too Fast Error is flash pattern 4-5 on Viking Professional VDB450 and RVDW324 built-in dishwashers with the second-generation control. The Pots/Pans light flashes four times and the Normal Wash light flashes five times. The control saw the water level rise faster than it should, which often points to a dishwasher that is not level, and it stops the cycle.

Common causes of Fill too Fast Error

Dishwasher not level in its opening
Inlet valve letting water in too quickly
Level sensing reading incorrectly

✓ One safe check you can try

1. Make sure the dishwasher is level front to back and side to side; place a small level on the door edge or the tub rim when the door is open. 2. Hold START for four seconds to reset. 3. Run a cycle. 4. If 4-5 returns, call us and we will check the leveling and the inlet side.

! Why to stop there

Leveling needs the dishwasher legs adjusted in the cabinet
The inlet and sensing side need testing if leveling is correct

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

Fill too Fast ErrorFill too Fast Error questions

Why would leveling matter?

If the dishwasher tilts, water collects at one end and the sensor sees the level rise too quickly. Correcting the level is the first thing to try, before anything else is replaced.

What if the dishwasher is level?

Then the inlet valve or the level sensing may be giving the wrong reading. We test both on site before recommending a part, and quote the price in writing.

Can I adjust the legs myself?

If you can reach the front feet safely, small turns are fine. If the dishwasher is built into tight cabinets, we can do the leveling during the visit for you.
