Viking Dishwasher Error Code E:16

E:16 indicates a drain pump blocked fault. The control system checks the pressure switch status with 5 seconds left in a drain cycle step, and if the switch is still closed at that point, the fault is triggered. This can result from a blocked drain pump, a defective pressure switch, or a problem with the main electronics board. It is also worth noting that this code is listed as not currently applicable to standard Viking units, though the fault logic is still present in the system.

You should not continue running the dishwasher when E:16 is active. The code indicates the unit was unable to complete a drain cycle, meaning standing water may be present in the tub. Running additional cycles with a blocked drain can stress other components and may lead to water overflow or further damage.

A reset may temporarily clear the E:16 code, but if the underlying issue has not been resolved, the fault will return as soon as the unit attempts another drain cycle. The pressure switch, drain pump, and electronics should all be inspected and tested before relying on a reset as a solution.

Some causes of E:16 are DIY-friendly, particularly clearing debris from the drain pump area. Remove the filter and inspect the pump for obstructions, and check that the drain hose is not kinked or clogged. If the pump motor or pressure switch has failed, those repairs involve electrical components and may be better handled by a qualified technician.

Repair costs vary depending on the root cause. Clearing a drain pump blockage yourself costs little to nothing. Replacing a drain pump motor typically runs in the range of $100 to $300 including parts and labor. A faulty pressure switch is generally less expensive, while a main control board replacement can range from $200 to $500 or more depending on availability.
