The fridge section of my Diplomat / Servis frost free fridge freezer is not cooling?

This may be caused if the door to the fridge or freezer section had not been fully closed. Moisture is pulled in and can cause an ice blockage to the duct which takes the cold air into the fridge section. Our recommendation is first to try the following process:-

  • Empty both freezer and fridge contents & turn off both fridge and freezer sections.
  • Put a cloth on the floor of the freezer section to collect any defrost water. It may take up to 48 hours to defrost but leaving the doors open should speed up the process.
  • Once defrosting has finished close the doors and switch both fridge and freezer sections back on but do not refill with food for at least six hours to allow the compartments to get down to correct temperatures.
  • If the problem is not solved or returns, then call our Hygena, Diplomat & Servis team on 01920 444020 and we can arrange a repair.

I cannot remove the child lock on my Diplomat ceramic hob?

First always refer to your instruction book. If you are unable to find it then possible methods of resetting to the manual mode are as follows:-

  • If there is a symbol of a ‘key’ then by pressing that it should unlock
  • If there is no key symbol then try pressing the minus key and front right hand zone key simultaneously and then operate the minus key alone. All steps need to be carried out within 10 seconds.
  • Still not working then call our Hygena & Diplomat customer care team on 01920 444020.

My Hygena / Diplomat oven won't switch on and there is an 'Auto' symbol in the timer display?

First always refer to your instruction book. If you are unable to find it then possible methods of resetting to the manual mode are as follows:-

  • Pressing the timer key which has the symbol of a hand above it - or
  • Pressing simultaneously the timer keys which have the symbol of a bell and a pot with steam above them and whilst keeping them pressed in, use the plus & minus key to reset the correct time.

The cooling fan on my Hygena / Diplomat oven stays on after I have switched the oven off?

The cooling fan will remain on until the surrounding temperature of the oven has reduced to an acceptable level. This could well be in the region of 30 minutes Plus before the cooling fan switches off.

My glass door shattered with a loud bang?

These are generally isolated incidents but the glass is specially toughened and is designed to fragment safely into many small cubes rather than sharp shards. The glass can be weakened for many different reasons such as a knock or scratches to the surface. Always ensure you use non abrasive materials when cleaning.

How often should I change the filters in my Hygena / Diplomat extractor?

There are two types of filter these being a grease filter which collects any fats and a carbon filter which extracts food smells.

  • Metal grease filters should be washed frequently with warm soapy water. DO NOT put in a dishwasher as they can discolour.
  • Disposable cloth or paper filters which should be changed before they become clogged or in the case of a type which has an indicator marking, when the markings fade.
  • Carbon filters are only required if you cannot duct through an external wall and therefore the extractor is used by re-circulating the air. For normal use they should be changed every 6 months or once the smells are not being neutralised.

I have a nasty smell coming from my fridge?

This can occur for example if milk is spilt inside the fridge and it travels down the drain hole and collects in the drip tray. We recommend using a small amount of neutralising fluid liquid poured down the drain hole, which is particularly helpful if your appliance is built in
