Understanding error code Dishwasher FB.

An asko dishwasher fb code, blink pattern L1+L12 on the legacy DW20.1 platform, points to a spray arm divider problem.

What FB means on your Asko dishwasher (asko dishwasher fb)

An asko dishwasher fb code is a legacy blink-code problem, shown as blink pattern L1 plus L12. It means the position contact for the spray arm divider, the mechanism that routes water between the upper and lower spray arms, is stuck continuously closed or continuously open rather than switching normally through the cycle. Because the divider controls which level of the tub gets full wash pressure at any given moment, a stuck contact leaves one rack consistently underserved.

Symptoms

Checking these symptoms against your Asko dishwasher keeps you from chasing the wrong problem, because look-alike problems call for different repairs. A dishwasher can show a single sign or several combined, creeping in gradually or landing suddenly after a surge, a leak, or fresh install work.

  • The top rack or bottom rack consistently cleans worse than the other
  • A clicking or switching sound that normally happens partway through the cycle is missing or continuous
  • Water pressure feels concentrated on one level of the tub throughout the entire wash
  • Blink pattern L1+L12 appears in the service menu

Common causes

Several separate problems can leave your Asko dishwasher showing these symptoms, so the causes below are ordered from the most to the least likely. Working through them in that order on your dishwasher tells a quick owner-level check apart from a problem that needs an experienced technician and the right Asko parts.

  • Divider contact switch stuck closed — mineral buildup or debris is holding the contact in one position
  • Divider mechanism jammed — a physical obstruction is preventing the divider from moving between positions
  • Wiring failure at the divider switch — a broken or corroded connection is preventing the switch state from being reported correctly

Troubleshooting steps you can try

Before you call for service, try each step on your Asko dishwasher in turn and watch how it responds. If a step on the dishwasher takes you near mains wiring, gas, a hot oven cavity, water, or a sealed component, stop and pass it to a qualified technician.

  1. Compare cleaning results between the top and bottom racks over a couple of cycles to confirm the pattern.
  2. Check for any visible obstruction around the divider valve, usually located near the base of the tub.
  3. Avoid forcing the divider mechanism by hand, since it is driven by a motor rather than manual adjustment.

Parts a technician may replace

When the problem on your Asko dishwasher is hardware-related, a technician inspects, tests, or replaces the spray arm divider, divider contact switch, and wiring. The exact part for your dishwasher comes from matching model, serial, and Art. No., and confirming the failure first means only what is genuinely broken on the dishwasher gets changed.

When to call a technician

A spray arm divider problem that shows a consistent one-rack cleaning pattern needs an experienced technician to inspect and test the divider valve and switch. This problem is rated Medium severity, so there is no emergency with your Asko dishwasher — but if FB keeps coming back on the dishwasher after the checks above, have a technician confirm the cause before any part is replaced.
