How to Deep-Clean the Interior on a Hotpoint RVM5160DHWW Microwave — Step-by-Step Instructions
Step-by-step instructions for the Hotpoint RVM5160DHWW (over-the-range microwave, 1.6 cu ft). Parts and access points can differ slightly by production year — the steps below cover the common layout for this platform, and the model notes flag its quirks.
Never use abrasive pads, scouring powder or oven cleaner inside a microwave — they damage the cavity coating and expose bare metal, which then arcs. Never remove the outer metal cabinet of a microwave. The high-voltage capacitor inside stores a charge that can kill you, and it holds that charge after the unit is unplugged. Every step in this guide stays outside the cabinet or inside the cooking cavity — if a repair needs the case off, it is a job for a technician.
Tools
- Microwave-safe bowl
- Soft cloth or sponge
- White vinegar or lemon
- Mild detergent
Parts
- None
Step by step
-
1 Steam the cavity loose
Put a microwave-safe bowl with a cup of water and a few tablespoons of white vinegar (or a halved lemon) inside. Run it for four to five minutes until it boils and steams up the cavity, then leave the door shut for five more minutes.
-
2 Unplug it before you scrub
Once the steam has done its work, pull the plug. You will be wiping around the door switches and the waveguide cover, and it should not be live.
-
3 Remove the plate and ring
Wash both in the sink like ordinary dishes. Most glass plates are dishwasher-safe.
-
4 Wipe the cavity down
The softened residue should come off with a cloth and mild detergent. Do the roof as well — it is where splatter collects and where people never look.
-
5 Clean the waveguide cover gently
Wipe it, do not scrub it. If it is charred, blistered or holed, replace it rather than cleaning it — that damage is what causes arcing.
-
6 Clean the door seal area
Wipe the flat sealing surface around the door and the matching face on the microwave. Food residue there stops the door seating properly against its switches.
-
7 Dry and reassemble
Dry everything, refit the ring and plate, and plug it back in.
Hotpoint RVM5160DHWW notes & error codes
Rental-grade over-the-range units are worth repairing for anything under about $150 because replacement includes an installation. Above that the landlord maths usually favours a new unit.

If you find rust that has eaten through the cavity wall, or paint damage exposing bare metal that keeps arcing after touch-up, the microwave has reached the end of its life. A cavity that cannot contain the energy safely is not repairable in any economic sense. If you'd rather skip it entirely, find a microwave repair pro near you →
