How to clean your Dimplex electric fire
Maintenance tips for a Dimplex Optimyst water vapour fire
Do you have a Dimplex fire that uses the Optimyst water vapour technology such as a Cassette or a Stove ? With regular use, a little periodic maintenance helps keep the flame effect looking its best. Always follow the instructions in your product manual, and ensure the appliance is switched off at the main switch before carrying out any cleaning.
You can also watch our maintenance video for a step-by-step explanation and extra tips.
Check the flame effect
Start by making sure the flame effect is working as it should. If the flames appear lower or uneven, it may be time to refresh the internal components.
Clean the interior components
Over time and even when the fire is not in use, dust, dirt or limescale can build up inside the unit. This may occur in:
· the water tank
· the water vapour outlet (nozzle)
· the underlying water reservoir (sump)
Your product manual will guide you through removing and replacing these parts safely and correctly.
You can clean the removable plastic components using warm water, a mild detergent, and a soft brush. Allow all parts to dry fully before refitting.
Check the air vents
Before reassembling, check the air vents at the base of the fire. Gently remove dust using a soft brush and a vacuum cleaner. Clear airflow helps the unit operate smoothly.
Inspect for Damage
If any part appears damaged or is not functioning properly, contact your Dimplex retailer or service partner for repair or replacement.
Clean the glass and decorative features
Once the inside is clean, check the decorative elements and wipe them if needed. Finish by polishing the glass panels on both sides to maintain a clear, streak-free view of the flame effect.
Maintenance tips for Other Dimplex electric fires
Dimplex electric fires featuring Optiflame technology are designed to be virtually maintenance-free. The only elements that may need occasional care are the glass panel (if your model includes one) and any decorative components inside the fire. Always follow the instructions in your product manual and ensure the appliance is switched off at the main switch before carrying out any maintenance.
Clean the glass panel
If your electric fire includes a glass front, clean both sides using a mild detergent and a soft cloth. Your manual will guide you through safely removing and replacing the glass when needed.
Refresh the decorative parts
Before re-fitting the glass, gently remove dust from any decorative logs, crystals or internal features using a soft brush. This helps keep the flame effect looking crisp and realistic.
Clear the fan heater (if applicable)
If your model includes a heater, lightly brush away dust from the outlet openings to maintain optimal airflow and performance.
Do it yourself or get help?
Most routine cleaning can be done easily at home. However, if you are unsure, or if any part seems damaged or not working as expected, contact your Dimplex retailer or service partner for professional support.
Final tip - check your remote control batteries Do not forget to check the batteries in your remote control from time to time. A quick battery refresh ensures your fire is always ready to deliver that unique atmosphere at the touch of a button.
All is ready? Then: enjoy!
