The combi ovens
ASKO 45cm combination microwave oven, Craft (OCM8487A1)
A microwave, a grill and a fan oven in one, at eye level above the big ovens. Reheat the sides, warm the plates, or use them as two more ovens when the big ones are full. The controls are the same as the big ovens: the function knob picks what it does, the selection knob sets it, and the confirm key (the tick) starts it.
Good for
- Reheating a plate or a bowl of soup in a few minutes
- Warming the plates while the roast rests
- Two more ovens when the big ones are full
- Microwave speed with a crisp, browned top
- Defrosting the thing you forgot to take out

Cook and crisp at the same time

- Step 2: Turn the function knob to Combi microwave and choose Large grill + fan + microwave.
- Step 3: Set the temperature and power — the manual suggests 200°C and 600 W — and a time. This one always needs a time.

Watch out for
- When the microwave’s on, food goes on the glass tray at level 1, and the racks and enamelled trays come out. Source: ASKO user manual, pp. 7, 22–23, 25 (opens in a new tab)
- Keep metal out when the microwave’s on, plates with a gold or silver rim included. A small piece of foil is fine if it’s clear of the walls. Source: ASKO user manual, p. 25 (opens in a new tab) · ASKO safety instructions, pp. 6–7 (opens in a new tab)
- Water can get hotter than boiling without bubbling, then erupt. Stand a plastic spoon in the cup and lift it out carefully. Source: ASKO safety instructions, p. 6 (opens in a new tab)
- Don’t run the microwave empty, and leave out eggs in their shells and anything sealed in a jar, tin or packet. Source: ASKO safety instructions, pp. 3, 7–8 (opens in a new tab)
- If something catches, switch it off and keep the door shut. That smothers it. Source: ASKO safety instructions, p. 7 (opens in a new tab)
