Update 04 - 10/10/2025
Permanent resolution: We can now confirm that Compressor Starter Relay Upgrade Kits will begin shipping during the week commencing 27th October 2025. These kits provide the permanent fix for the overheating issue and will return all E4 dispensers to full, safe operation.
Each kit will include:
• A new specification compressor starter relay,
• A new circuit board designed to ensure compatibility with the updated relay,
• Full pictorial installation instructions, and
• A link to a detailed instructional video to guide your technicians through the process.
Alongside the hardware upgrade, each E4 unit will also require a software update. Due to the nature of software key management, individual keys will not be provided with each kit. Instead, every distributor will receive a reusable software key for each of their technicians, which can be used repeatedly across multiple upgrades.
Technician training: To ensure a smooth rollout, we will be hosting training webinars to familiarise your technicians with the upgrade process. These will provide a step-by-step demonstration and the opportunity to ask questions anonymously. This is in addition to the pictorial installation instructions and accompanying video, which will act as a reminder. To enrol your technicians, we will send you a link to submit their names and email addresses so we can send direct webinar invitations and provide access to their reusable software keys. Please do not submit technician details until instructed to do so – we must ensure accurate data collation and software key allocation. Further details on how to record completed upgrades — for the purpose of applying the renewed 12-month warranty to each updated unit — will be shared as soon as the process is finalised.
Update 03 - 06/10/2025
Borg & Overström continues to work closely with our sub-assembly manufacturing partner to finalise and verify a permanent resolution to the E4 compressor starter relay issue. Lifetime testing of the replacement component remains our highest priority to ensure complete safety and long-term reliability. While we cannot offer direct commercial compensation at this stage, we are committed to supporting our distributor network by renewing the 12-month warranty on every updated unit and extending a 5% discount across all models throughout the 2026 trading year. We sincerely thank our partners for their continued patience, professionalism, and collaboration as we work through this process together.
Update 02 - 30/09/2025
Our R&D and Quality teams are currently completing life testing of a replacement compressor starter relay. Once testing is successfully concluded and the part is fully verified, we will issue a clear roll-out plan along with step-by-step instructions for updating each affected dispenser. We expect to share this rollout plan with you within the next few days.
Update 01 - 25/09/2025
