Mercury / Electric hob / BR8
A control knob is loose
Describe whether the outer knob is loose, the shaft feels unusual or the selected setting no longer changes. Stop using a control that cannot operate reliably. Do not grip an exposed shaft with tools or force a damaged fitting. The model determines the correct control arrangement and any suitable repair.
Compare this observation: one zone will not heat
Tell us the hob type and exact zone that no longer heats. Describe whether other zones and the display remain normal. A zone position is not sufficient to identify a component, especially across different technologies. Keep the glass and underside assembled, and supply the full model from a safely visible label.
The equipment shares its position.
Tell us about stacked equipment, neighbouring cupboards or other fittings that limit access. A visible connection is not an invitation to loosen it.
For the Swanley address
Swanley enquiries need the complete BR8 address and the actual appliance or specialist unit. The online request starts a conversation; it does not reserve a visit by itself.
Read the identity, not just the badge.
Quote the complete model and serial or service number from a safely visible label. Similar product names can hide different components. If the label is concealed, leave the appliance in place and tell us the model is unknown.
We do not invent a model catalogue for this brand. Send the exact label details for an individual check.
A useful question for the enquiry
Does “a control knob is loose” establish the failed part?
No. Describe that observation separately from “one zone will not heat”. Explain whether they began together or at different times, and include the fitting detail: the equipment shares its position. The inspection can then consider the symptoms and safe access together.
