What ER05
actually means.

When a Hestan Smart Burner shows ER05, it tried to relight several times without success and then ended the cooking cycle. Hestan points to clogged burner ports or a worn igniter.

What to do when ER05 shows on the stove

Kind of codeIgnition and burners

The stove asked a gas burner or the oven to light and never saw a flame, or it kept sparking once the flame was already burning. A burner cap sitting off-center and an igniter still wet from cleaning are ruled out before the spark switch, the spark module or a valve is replaced. A smell of gas outranks every code on the display: get everyone out, and call the gas utility once you are outside.

Usually leads toIgniter and spark switch repair

Gas stove burners that tick without lighting, keep ticking after they light or tick with every knob off, traced to the electrode, the spark switch or the spark module.

Shows up asGas Stove Won't Light

None of the gas burners will catch: you hear clicking with no flame, or there is no click at all, or the burners lit yesterday and now nothing happens.

Before you book,
in this order.

Each step comes from Hestan's own guidance for ER05 on its stoves. Follow it to the end: the last card says whether this is a visit.

01

Turn the burner off and let it cool; if you smell gas, leave the knobs off, leave the house and call the gas utility from outside.

02

Clean the burner ports and the igniter, and make sure the burner cap sits flat.

03

Try again; if ER05 returns, book a visit for the igniter.

It usually turns into igniter and spark switch repair. Book with the code and the model number.

What not to do

ER05 is not a pan reading problem like ER01. The flame itself did not start.

Questions
about ER05.

Can I clear ER05 myself?
Turn the burner off and let it cool; if you smell gas, leave the knobs off, leave the house and call the gas utility from outside. If it comes back, it needs a visit.
Why did my Hestan Smart Burner give up and show ER05?
It tried several times to light and could not, so it stopped the cycle to avoid releasing gas. Clogged ports or a worn igniter are the usual reasons.
How do I clean the burner ports on my Hestan stove?
With the burner cool, lift off the cap and clear the ports with a stiff brush or a straightened paper clip. Keep water out of the igniter and let everything dry before lighting.
Should I worry about gas when ER05 shows on my Hestan stove?
The stove stops the cycle after the failed attempts. If you smell gas, do not try again; leave and call the gas utility from outside.

Back to your everyday

Still showing ER05?

Book with the code written exactly as the stove shows it, the full model number, and whether you notice any smell of gas or hot wiring — when there is a code, that is where the diagnosis starts.
