Do you have a faulty Instant Pot Vortex plus air fryer that just displays Close Basket and won’t start? Or maybe the air fryer just stops after a short time and shows Close Basket? If so here’s three ideas to fix it without having to send it back or buy another. Updated 22 Dec 2024.

1. Faulty Microswitch

Our problem with the Vortex Plus was due to the tiny microswitch on the top front centre of the housing – see below. The basket failed to engage fully with the switch button even when pushing the basket fully into place.

We took delivery of our Vortex Plus as air fryers were becoming a popular way to reduce energy costs. So when the Close Basket problem became apparent after a few runs we decided to keep it rather than ask Amazon for a refund. We found by pulling up on the basket handle as you pushed it into place the Close Basket prompt disappeared. We could hear a faint click as the switch registered the drawer was in place.

After several months the switch problem became more frequent and I searched for a simple fix. First I cut a small piece of aluminium tape and wrapped it around the top basket wedge that engages with the switch. A double thickness worked well and the Close Basket nagging display disappeared. But it was short lived, the aluminium tape adhesive became weak with heat and wore away.

The tape proved the switch or basket position were to blame, but there’s no visible adjustment to either.

Next I applied a very small spot of high temperature epoxy to the end of the push button switch. The idea was to make the push button longer. After waiting 24h for the epoxy to cure I gently closed the basket and the glue broke off. I used very fine sand paper to roughen the tip of the switch button but the epoxy still failed to adhere.

De-greasing with alcohol may allow a stronger bond but the slippery plastic suggests it’s not suitable for the resin I used.

Opening a tin of tuna treat for our cat I wondered if a thin tin strip folded over the basket wedge would work.  Take care with tin snips and sharp metal edges! I found it does not take long to cut a 10mm square piece from a lid and fold into shape with two pairs of round nosed pliers.

I left a small tail to fold over the front to engage with the round push button end. The tin piece slides over the top of the basket wedge and works well. I used the high temperature epoxy to secure the tin and avoid it ending up in a meal!

The Close Basket problem has now gone and the Vortex Plus has helped reduce our electricity bills by avoiding the inefficient Neff grill and oven. If you also have a Neff combi microwave oven read more here.

If your Instant Pot Vortex Plus air fryer suffers from the same ‘Close Basket‘ fault and you too can’t return it as it’s out of warranty then try this simple fix rather than throw it away.

2. Tighten loose screws

Thanks to David (see comments below) for this tip. I checked our Vortex, now two years old. The Close Basket warning was being displayed every time unless we pulled the basket up as we forced it back in. This was despite the tin plate fix, which you can see below had worn.

Don’t attempt this if the heating element is still hot!

I found all the screws inside the unit and drawer had become loose just as David suggested. I used a short handled crosshead driver to tighten the ones inside see pictures below. Many needed a couple of turns so had worked quite loose. Don’t forget the three screws at the rear as well. This improved the problem and Close Basket did not show first time I tried it. But it still showed up after a few more goes.

I turned to the basket drawer and checked the 4 screws holding the front in place. In my case two of them were loose, so I tightened and the Close basket warning now only shows occasionally, so long as you push firmly. I suspect it really needs the microswitch replacing (see next tip) but I can confirm tightening the screws helped in my case.

3. Replace microswitch

If you are willing to try opening up the air fryer – making sure you disconnect from mains power first – you could try replacing the microswitch inside the unit. Thanks to Ed & Chris for the details in the comments below.

The suggested microswitch can be found on Amazon – Ed suggested works – https://www.amazon.com/Microwave-Switch-Replacement-KW3AT-16-Normally/dp/B083CNS17V

Use a plastic pry bar to separate the top and bottom of the case. There are many available made to remove car upholstery and trim.

Post script notes:

  • On our air fryer the basket switch needs a firm action to operate. Over a few months use the plastic wedge wore away preventing firm contact to register. I’d be surprised if this problem is not more widespread and indicates a manufacturing or design defect.
  • In engineering terms, the switch contact hysteresis is either too high – i.e. the spring tension is too great – or the radius profile between the basket wedge and push button too shallow to provide enough force.
  • Adding a thin tin cover over the plastic wedge replaces the worn plastic and the sharper radius formed by the tin tail provides more force to operate reliably.
  • Overall the Instant Brands design is very good, the air fryer works well and feels substantial so it’s a pity such a small part can lead to early product failure. I trust this is not built in obsolesce and Instant Brands will improve future models in this regard.
  • Despite repeated attempts to contact Instant Brands support they have failed to respond to my questions and in view of this I will not be buying from them again and can’t recommend this brand of air fryer.
