Blomberg Dishwasher: flooding
What is this symptom?
Experiencing flooding with your Blomberg dishwasher? Water may be overflowing onto the floor or accumulating in the base tray, triggering the anti-flood protection system. This issue often occurs during or after wash cycles and can lead to significant water damage if not addressed promptly.
Important Tips for Blomberg Models
- Blomberg dishwashers may display error code E07 when the anti‑flood/leak detection system is activated, indicating water in the base tray requiring inspection of float switch and internal leaks.
Possible Causes
Clogged drain/filter leading to improper drainage and backup overflow
How to Identify: Water remains in tub after cycle, food debris visible in bottom filter, slow/no draining; water backing up toward door.
Part: Drain hose / filter assembly
Worn/damaged door gasket allowing water to leak during cycles
How to Identify: Water leakage around door perimeter during wash; visible cracks or deformation in gasket.
Part: Door gasket (seal)
Water inlet valve stuck open causing overfilling
How to Identify: Water continues to fill even when cycle should not be adding water; flooding even with short cycles.
Part: Water inlet valve
Internal leak detected by Blomberg anti‑flood system (e.g., E07 error)
How to Identify: Dishwasher displays error E07 and stops; water present in base tray under unit.
Part: Base tray / leak detection circuit
