Zanussi Boiler Error Codes / Fault Codes

Zanussi was established in 1916 and is owned by The Electrolux Group. Zanussi is also the world’s second-largest appliance maker, known for manufacturing home appliances in addition to boilers.

Zanussi claims that they are widely recognised for the quality of their innovative products and distinctive modern design.

This boiler brand consists of two boiler models, the Zanussi Ultra Combi in outputs of 30kW and 35kW and the Zanussi Ultra System 15kW to 30kW.

Zanussi boilers are compact and lightweight so that they can be installed neatly inside your standard kitchen cupboard. They are designed with a simple, easy-to-read display screen and simple diagnostics for complete control of your boiler as well as compatibility with several controls.

If your boiler is in warranty, then contact Zanussi boilers and they should come out to fix it as long as you have met the conditions of your warranty (getting an annual boiler service, etc).

If your boiler is out of warranty and rather than put money into fixing it you think it might be worth getting a quote on a new boiler, then give WarmZilla a try. Prices start from £1489 including installation, wireless controls, system cleanse, system filter, and a guarantee lasting between 5 & 14 years depending on which boiler model you select.

WarmZilla offers boiler finance, with 0% interest over 2 years on selected boilers. Our lenders have a very high acceptance rate, even if you have a bad credit history.

Hopefully, it won’t cost much to get your Zanussi boiler fixed but if it’s over £500 and you’ve had it a good few years then it may be worthwhile getting a WarmZilla boiler quote.

If you’re unsure what type of boiler you are looking for or what kW output you need for your home, we have blogs that cover these subjects as well.

WarmZilla does not stock Zanussi boilers, however, there are many other combi, system, and regular boilers from boiler brands that we do sell. We have added some other blogs below that also may help you find the best boiler for your home.
