Quick answer: Bosch washing machine error code E:30/-80: drainage fault: blocked or kinked outlet hose. The most common cause is drain pipe or water outlet hose blocked. Try this first — check and clear the hose. If that does not clear it, clean the drain pump.

What causes the E:30/-80 error?

  • Drain pipe or water outlet hose blocked
  • Outlet hose kinked or sharply bent
  • Outlet hose connected higher than 39 inches (1 meter)
  • Unsuitable hose extension fitted
  • Drain pump blocked
  • Pump cap not screwed in fully
  • Excessive detergent foaming

How to fix Bosch E:30/-80 — step by step

Work through these in order, from simplest and safest first. Stop as soon as the code clears.

  1. Check and clear the hose
    Make sure the outlet hose is not kinked or blocked, sits no higher than 39 in. (1 m), and has no unsuitable extension pieces.
  2. Clean the drain pump
    Open the pump access flap, remove the pump cap, clear any debris, then screw the cap back in all the way so its handle sits vertical.
    Safety warning: Unplug the machine and have towels ready; residual water may be hot.
  3. Tame excess foam
    If suds are heavy, mix one tablespoon of fabric softener with about 2 cups (0.5 L) of water, pour into compartment II, and reduce detergent on the next wash.

When to call a technician

Stop and call a qualified technician if any of these apply:
  • Drainage still fails after the hose and pump are clear
  • The pump is silent or jammed even after cleaning
  • The code returns on every cycle
